No, this is an XXE bug. Here is why:
in a CSS, a reference to the attribute A of the element which is the
subject of the selector is specified using construct attr(A).
CSS being case insentive, all CSS identifiers are converted to
lower-case character strings (except in selectors).
Therefore, if you specify attribute name A as an identifier, A is
automatically converted to lower-case, which may be a problem because
XML is case-sensitive.
In order to specify non-lower-case attribute names, one must specify A
as a quoted CSS string rather than a CSS identifier. Example: specify
attr("HRef") rather than attr(HRef).
Unfortunately, a bug prevented XXE from accepting construct
attr(string).
I have released Patch 3 (
http://www.xmlmind.com/xmleditor/download.shtml ) which fixes this bug.
Do not forget to change attr(Name) to attr("Name") in your style sheet.
