a few minor element changes

[Chris Jones PISCO Project]

Hi folks,

I did a quick grep through the .xsd files to find elements with truncated 
names as part of bug 497.  Here's the list...while people are editing 
these files individually, you might change the element names to full 
names, otherwise I'll make a pass again when things are checked in.
