200 Chapter 14 Customizing the Development Environment
Exploring the new VTML structure
If you modified existing language elements or added new elements, such as custom
tags, in previous versions, you will notice a significant change in the Extensions
folder and in the Extensions\MarkUpTags file. In previous releases, the MarkUpTags
file was a repository of VTML coded information for all the supported languages. It
was a large complex document. This release takes a more modular approach to
VTML language support by using the new
vtinclude tag to group languages in
discrete files that are then included in the MarkUpTags file.
To modify existing elements, you first identify the language file in MarkUpTags.vtm,
then open that file in the Extensions\Includes folder to make your changes.
