The XSLT project page on webkit.org mentions a XSLT component in Bugzilla. There is no such a component listed.
In the past we have used the XML component for XSLT. The description for the XML component reads "For bugs in XML support other than XML DOM, including XSLT, XMLHTTPRequest, XML Parsing, etc."
Given that we rely on libxslt for XSL, I don't think that there is need for a separate component. As Sam said, you can just use XML.
Then it would be nice if the webkit xslt project page is altered.
Just below the subtitle Get Involved! is a link, pointing to the XSLT component in bugzilla. Just change XSLT in both the link text as the link itself would fix the problem...
