I am almost done with the code refractoring of XPontus. I've been playing with antlr and met some interesting guys on IRC. I want to provide the new release before christmas and add all the features that have been requested. Hopefully code completion will be ready in time. At this moment I am getting used to antlr lexer support.

As antlr3 gives me the offset of a token(keyword, etc.) in a line I think I will switch from jedit syntax package to antlr3. The code completion will be based on sidekick plugin from Jedit. The dtd are stored in a cache and a list of possible values are built based on the current token.
