/**
This clause describes the OCL Standard Library of predefined types, their operations, and predefined expression templates in the OCL.
This sub clause contains all standard types defined within OCL, including all the operations defined on those types.
For each operation the signature and a description of the semantics is given.
Within the description, the reserved word ‘result’ is used to refer to the value that results from evaluating the operation.
In several places, post conditions are used to describe properties of the result.
When there is more than one postcondition, all postconditions must be true.
A similar thing is true for multiple preconditions.
If these are used, the operation is only defined if all preconditions evaluate to oclText[true].

heading:1[Introduction]

The structure, syntax, and semantics of the OCL is defined in Clauses 8 (“Abstract Syntax”), 9 (“Concrete Syntax”),
and 10 (“Semantics Described using UML”).
This sub clause adds another part to the OCL definition: a library of predefined types and operations.
Any implementation of OCL must include this library package. This approach has also been taken by e.g., the Java definition,
where the language definition and the standard libraries are both mandatory parts of the complete language definition.

The OCL standard library defines a number of types.
It includes several primitive types: UnlimitedNatural, Integer, Real, String, and Boolean.
These are familiar from many other languages. The second part of the standard library consists of the collection types.
They are Bag, Set, Sequence, and Collection where Collection is an abstract type.
Note that all types defined in the OCL standard library are instances of an abstract syntax class.
The OCL standard library exists at the modeling level, also referred to as the M1 level, where the abstract syntax is the metalevel or M2 level.

Next to definitions of types the OCL standard library defines a number of template expressions.
Many operations defined on collections map not on the abstract syntax metaclass FeatureCallExp, but on the IteratorExp.
For each of these a template expression that defines the name and format of the expression is defined in 11.8, Predefined Iterator Expressions.

The Standard Library may be extended with new types, new operations and new iterators.
In particular new operations can be defined for collections.

Certain String operations depend on the prevailing locale to ensure that Strings are collated and characters are case-converted
in an appropriate fashion.
A locale is defined as a concatenation of up to three character sequences separated by underscores,
with the first sequence identifying the language and the second sequence identifying the country.
The third sequence is empty but may encode an implementation-specific variant.
Trailing empty strings and separators may be omitted.

The character sequences for languages are defined by ISO 639.

The character sequences for countries are defined by ISO 3166.

‘fr_CA’ therefore identifies the locale for the French language in the Canada country.

Comparison of strings and consequently the collation order of Collection::sortedBy()
conforms to the Unicode Collation algorithm defined by Unicode Technical Standard#10.

The locale is ‘en_us’ by default but may be configured by a property constraint on OclAny::oclLocale.

The prevailing locale is defined by the prevailing value of oclLocale within the current environment;
it may therefore be changed temporarily by using a Let expression.
let oclLocale : String = ‘fr_CA’ in aString.toUpperCase()

heading:1[Iterators]

This sub clause defines the standard OCL iterator expressions.
In the abstract syntax these are all instances of IteratorExp.
These iterator expressions always have a collection expression as their source,
as is defined in the well-formedness rules in Clause 8 (“Abstract Syntax”).
The defined iterator expressions are shown per source collection type.
The semantics of each iterator expression is defined through a mapping from the iterator to the ‘iterate’ construct.
This means that the semantics of the iterator expressions do not need to be defined separately in the semantics sub clauses. 

In all of the following OCL expressions, the lefthand side of the equals sign is the IteratorExp to be defined,
and the righthand side of the equals sign is the equivalent as an IterateExp.
The names source, body, and iterator refer to the role names in the abstract syntax:

source	The source expression of the IteratorExp.

body	The body expression of the IteratorExp.

iterator	The iterator variable of the IteratorExp.

result	The result variable of the IterateExp.

heading:2[Extending the Standard Library with Iterator Expressions]

It is possible to add new iterator expressions in the standard library.
If this is done the semantics of a new iterator should be defined by mapping it to existing constructs,
in the same way the semantics of pre-defined iterators is done (see sub clause 11.9)

/**
Collection is the abstract supertype of all collection types in the OCL Standard Library.
Each occurrence of an object in a collection is called an element.
If an object occurs twice in a collection, there are two elements.

This sub clause defines the properties on Collections that have identical semantics for all collection subtypes.
Some operations may be defined within the subtype as well,
which means that there is an additional postcondition or a more specialized return value.
Collection is itself an instance of the metatype CollectionType.

The definition of several common operations is different for each subtype.
These operations are not mentioned in this sub clause.

The semantics of the collection operations is given in the form of a postcondition that uses the IterateExp of the IteratorExp construct.
The semantics of those constructs is defined in Clause 10 (“Semantics Described using UML”).
In several cases the postcondition refers to other collection operations,
which in turn are defined in terms of the IterateExp or IteratorExp constructs.
