Add Support for Internet Explorer's Conditional Comments
--------------------------------------------------------

                 Key: JBPORTAL-1498
                 URL: http://jira.jboss.com/jira/browse/JBPORTAL-1498
             Project: JBoss Portal
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
          Components: Portal Theme
    Affects Versions: 2.6.CR1
         Environment: All
            Reporter: Andy Pemberton
         Assigned To: Julien Viet


Currently, JBoss Portal's theme and layout architecture relies on XML deployment descriptors for several objects.  For example, the portal-theme.xml is used to create themes (javascript and css) that will be applied to layouts.

The request I have is this: given the XML deployment descriptors, add in support for Internet Explorer's Conditional Comment system. 

Conditional Comments have been a feature of IE since IE5. Basically, Conditional Comments are specially formatted HTML comments that allow web developers to target specific markup to Internet Explorer. Typically, Conditional Comments are used to import specific Cascading Style Sheets (CSS) to HTML pages to handle IE-specific CSS defects. 

Currently, the lack of support for Conditional Comments is caused by the fact that Conditional Comments rely on XHTML-based comments, which are thus filtered out at the portal-theme.xml level. I considered adding this request as a defect, but decided against it as not reading in comments in an XML deployment descriptor is quite logical, and of course - IE's conditional comment system (though useful) is counter-intuitive.
