		<description>&lt;p&gt;Thanks for yet another great article Sam.  Do you have any suggestions or advice for someone looking to design a code model for a new VS language (as a 3rd party extension)?  I&#039;m using ANTLR to do lexing and parsing, but I&#039;m still trying to figure out the best way to design the AST such that I can perform reparses quickly when the text in the editor is changed (and only reparse what I need to).  I&#039;m only just now digging into the VS2010 documentation to see if they have automated tools and services that can help keep my AST up to date as the text changes.  Thanks in advance for any comments you might have, and I look forward to more of your great articles on Visual Studio extensibility and ANTLR.&lt;/p&gt;
