There is significant difference of opinion within the WG as to what
the preferred style is.  There have been some lengthy threads on
XML-DEV under Roger Costello's "Best Practices" banner discussing this 
issue.  I don't expect a single style will suit everyone, or be
unequivocally recommended.

No, although writing a stylesheet to produce this from the reflected
PSVI is a project on my stack.

-k keep going, i.e. try to validate even if compile-time errors in the 
   schema(s) are found

-w show warnings (xsi:type and a few other things) -- more like
   debugging notices than warnings

-r produce reflected PSVI output

-t show timing splits

Python execution profiling, see the Python documentation.  Again, this 
is really developer debugging information.
