<searchtitle>Creating a new document type definition (DTD)</searchtitle>
</titlealts>
<shortdesc>A document type definition (DTD) contains a set of rules that can
be used to validate an XML file. After you have created a DTD, you can edit
it manually, adding declarations that define elements, attributes, entities,
and notations, and how they can be used for any XML files that reference the
DTD file.</shortdesc>

opens in the DTD editor. In the DTD editor, you can manually add elements,

file, and want to later re-open it in the DTD editor, double-click it in the
Navigator view.</p></result>
