I would just try de-emphasising the extended attributes, and perhaps 
emphasising the identifiers of attributes, operations, etc.

I'm by no means a designer, but attached is something that looks OK to 
me.  You might find it a bit too colourful and source code editor like. 
  I missed that you said "given the current markup" before I did this, 
so adapting styles like this might not be so easy without modifying your 
markup.  It should be easy to play with the styles if you want to.  I 
also introduced some more newlines where I thought it helped make it 
more readable.
