Modifying XSHD file

Hi folks,

Firstly, I'd like to thank you for your great work on SharpDevelop

I've a problem with syntax highlighting in TextEditor (Not Avalon)

I want to add extra nodes & attributes in the file so i can parse them and do some work but when i try to do that, The highlighting stops working

I want to modify a keyword node from:

<Key word = "And" />

TO

<Key word = "And" context="test" />
