Hi Dave,

I can not answer all your questions, but some I can.

You were asking for the status of the mobile profile. Well, as published on
the mailing list yesterday, the major revision is nearly ready and this
includes the mobile profile according to the recent specification.

Commenting it in had not only to be done in StyleSheetCom.java, but is now
done in all the sources in CVS. The fix you mentioned for Css2Style.java to
include the CssColumnSpan is indeed a valid fix that I had already noticed
and will be fixed today by me in the CVS repository. Why it was commented
out was probably a misunderstanding somewhere. I can't tell, I'm not the
only one who has made changes to the CSS validator.
There may be a few obsolete Java files in the repository, but if there are
any, there will be only very few and they should not bother your compiling

I run the CSS validator on Jigsaw 2.2.0 and have
<INSTDIR>/Jigsaw/classes/xerces.jar included in my CLASSPATH, so that that
version of Xerces is used.

Hopes this was useful information for you.
