Extending IntelliJs syntax highlighting for HTML

Hi!
I am quite new to plugin development for Intellij and perhaps some of you could help me with a little problem
The Plugin should be a little helper for developing web-applications with the wicket framework (http://wicket.sourceforge.net).
Wicket HTML pages use some tags in extension to the normal HTML. For example:
<wicket:link> or allows the placement of a "wicket:id" attribute within any other tag. A full list of tags can be found at http://www.wicket-wiki.org.uk/wiki/index.php/Tags.
What I want to achieve is the support of those tags within IntelliJ. At first, that they're recognized as "valid" and IntelliJ does not complain about for example the "wicket:id" being placed within a normal HTML tag.
My problem is that I don't know where to start. If anyone could help me to find a point to start off i would be very happy.
Thanks in adavace.

best regards,
Daniel
