XML simply doesn't have "complex type" attributes, it's something we 
have to live with. I think it worked out very well in previous cases: 
XPath in XSLT and Path data in SVG (or even the style attribute in HTML)

And in this case there are more advantages:
- It might be a choice between having information in a micro-syntax,
   or not having the information at all.
- N3 already seems to be the preferred syntax for RDF

It's not that hard to create a complete N3 document from a "properties" 
attribute (add namespace prefix declarations, set the base uri, prefix 
the value of the about attribute in <> and append a dot.) Then use N3 
tools to either get the triples or RDF/XML.
