This generates an "Invalid pseudo-element "Description"" parsing 
error in Amaya. Is this a bug? The "\" should cancel the special 
meaning of the ":" character in CSS.

I should have said "some" other browsers as Firefox do not allow 
"custom" tags in HTML. This example has also been tested with other 
file-types, e.g. xhtml and xml with the following browsers:

Amaya   11.3.1
Chrome  6.0.472.63
Firefox 3.6.11
IE      9 beta
Opera   10.53

The files have been served locally on a Windows 7 system as:
html:  text/html
xhtml: application/xhtml+xml
xml:   text/xml

The results are:

           html     xhtml     xml
Amaya       -        -        -
Chrome      -        x        x
Firefox     -        x        x
IE 9b       -        x        x
Opera       -        x        x

rdf\:Description {display: none}

           html     xhtml     xml
Amaya       -        -        -
Chrome      x        x        x
Firefox     -        x        x
IE 9b       x        x        x
Opera       x        x        x

<rdf:RDF ... style="display: none">

           html     xhtml     xml
Amaya       x        x        x
Chrome      x        x        x
Firefox     -        x        x
IE 9b       x        x        x
Opera       x        x        x

Any comments?
