RDF metada <rdf:RDF> in SVG

[GoogleCodeExporter]

PROBLEM:

I have been using SVG inserts to scale elements in ePUB documents. The files 
validate cleanly in every detail, except that ePUBcheck flags up <rdf:RDF> as 
invalid. Looking at the W3C website I don't think this is correct. It is valid. 
The files work perfectly, so perhaps this is a bug in ePUBcheck? This was with 
version 3.0b4.

METHOD:

What steps will reproduce the problem?
1. include an SVG image in the flow of the document, correctly inside a <div> 
tag.

2.Make sure there are no errors at all in the ePUB, then make sure that the 
plain SVG contains <rdf:RDF> metadata, which typically it will.

3.run the file through ePUBcheck version 3.0b4.

RESULT:

ePUBcheck correctly identifies that the file is in fact ePUB 2.01. Everything 
passes validation, except for each SVG file the <rdf:RDF> element is said to be 
invalid.

EXPECTED:

As far as I can see it isn't invalid, so I would expect a complete 'No errors' 
result.

PLATFORM:

This was with version 3.0b4. I stopped using version 1.2 because that said 
there was a font type specification error in the .opf file that also didn't 
seem to be correct and because I am beginging to develop for ePUB 3. Version 
3.0b4 does not report the font error, so presumably that has been fixed.

I am using Windows 7 64 bit 

ADDITIONAL INFO:

My objective is to create beautiful eBooks as eBooks, not as fallout from 
print, so I am probably pushing the boundaries of what may be done with ePUB 
2.01; however, everything I do is validated by other checks and the files work 
well in all the major e-readers on the market, in desktop testing and on the 
iPad.

I haven't tried version 3.0b5 yet. This doesn't seem to be amont the fixes 
listed though.

The schema for SVG 1.1 referenced by the EPUB 3 spec and used by EPUBCheck is 
known to be incomplete. It is correct that the svg metadata elements allows any 
content including RDF, and the validation wrongly reports this as an error. The 
fix of the schema will hopefully be part of the upcoming minor revision to 
EPUB, and will then be used by EPUBCheck. For now, ignore this error report.
