I strongly agree (3 with 1 for compatibility).  In addition to the two niceties 
Michael suggests, I would like the parser also to parse the namespace PIs.  Not 
only does this save all applications from writing the same code, parser writers 
probably already have low-level functions they can adapt/use for this purpose.  
The parser would use a separate callback (not processingInstruction) to return 
the namespace information.
