The *namespace* and *text-width* issues are now fixed, but the 
*font-weight : italic* fault in default.css remains.

I also note that the W3C CSS validator reports for styles.css:

    11     document, div.document     inherited is not a hyphens value :
    inherited

That validator (and others) also report a number of issues for the 
@counter-style rule, which seems to have changed significantly since 
this CSS was developed. Validators report a number of smaller issues as 
well.

I understand that export output is a low-priority feature.
