discussion of the Creative Commons Metadata work

[Lisa Rein <lisarein AT finetuning.com>]

isn't the parser skipping it because it's commented out?

you'll need to aggregate the pages and then strip out the rdf and 
create "real" xml files (with declarations and things), and then it 
should parse, right?

just a guess at what the problem might be.  Comments are the same in 
XML as HTML, so the parser is working correctly.
