Could you explain how you came up with the XML schema design?  I suppose you 
just made something up that went along with the existing XML output.

I would like to see more integration with the spirit of the existing XML 
functionality.  For example, instead of things like

"<runtime ms=\"%.3f\" />\n"

we ought to be using XML Schema data types for time intervals and so on.

We might also want to use an XML namespace.

Table and index names should be escaped using the existing escape mechanism 
for identifiers.  There might also be encoding issues.

It would also be interesting if EXPLAIN could optionally be a function that 
returns a datum of type XML, to allow further processing.

Any thoughts on these issues?
