Dialog Definition Files

The structure of the included files referenced in MarkUpTag.vtm and in ExpressionElements.vtm is very simple. They contain a set of category and element tags. Category tags can contain any number of elements or other nested category tags.

<cat ... main category>
  <cat ... sub-category No.1>
    <e ... >
    <e ... >
    <e ... >
  </cat>
  <cat ... sub-category No.2>
    <e ... >
    <e ... >
  </cat>
</cat>

The following section explains how to create and update category and element tags.

Category tag

The cat tag defines a category in the Category tree. The Category tree populates the left pane of the Tag Chooser and Expression Builder.

For syntax and usage information, see cat in the VTML Reference.

Element tag

The e tag defines elements within a category. These elements populate the right pane in the Tag Chooser and the Expression Builder.

For syntax and usage information, see e in the VTML Reference.
