The WTP JSP Source Editor provides validation and content assist for any
3rd party JSP tags and their attributes.
The WTP Web Page Editor offers support for visual development, semantic
validation and content assist for the JSF Core and HTML tag libraries
and a subset of the Apache MyFaces Trinidad tag library. Support for the
Tomahawk library is not planned in the current release. That said, the
design time support for these tag libraries are all built on extensible
frameworks and hence it is possible for interested users to provide
support for any JSF tag library. We also welcome such contributions to the
project.
Hope this answers your questions. Thanks for your interest in the JSF
Tools project.
