<xs:attribute name="checkpoint-policy" use="optional"
type="xs:string">
<xs:annotation>
<xs:documentation> Specifies the checkpoint policy that governs
commit behavior for this chunk. Valid values are: "item" or
"custom". The "item" policy means the chunk is checkpointed after a
specified number of items are processed. The "custom" policy means
the chunk is checkpointed according to a checkpoint algorithm
implementation. Specifying "custom" requires that the
checkpoint-algorithm element is also specified. It is an optional
attribute. The default policy is "item". However, we chose not to
define a schema-specified default for this attribute.
</xs:documentation>

</xs:attribute>
<xs:attribute name="item-count" use="optional" type="xs:string">
<xs:annotation>
<xs:documentation> Specifies the number of items to process per
chunk when using the item checkpoint policy. It must be valid XML
integer. It is an optional attribute. The default is 10. The
item-count attribute is ignored for "custom" checkpoint policy.
However, to make it easier for implementations to support JSL
inheritance we abstain from defining a schema-specified default for
this attribute. </xs:documentation>
</xs:annotation>
</xs:attribute>
<xs:attribute name="time-limit" use="optional" type="xs:string">
<xs:annotation>
<xs:documentation> Specifies the amount of time in seconds before
taking a checkpoint for the item checkpoint policy. It must be
valid XML integer. It is an optional attribute. The default is 0,
which means no limit. However, to make it easier for
implementations to support JSL inheritance we abstain from defining
a schema-specified default for this attribute.
When a value greater than zero is specified, a checkpoint is taken when
time-limit is reached or item-count items have been processed,
whichever comes first. The time-limit attribute is ignored for
"custom" checkpoint policy. </xs:documentation>

<xs:attribute name="skip-limit" use="optional" type="xs:string">
<xs:annotation>
