Re: adding xlink:type attribute

Hi John,

OK, so my adding xlink:type="simple" does not break anything.  Good.

But

So I am asking, politely I hope, to make xlink:type required, so that we 
conform to the xlink spec.
For starters, could all the thredds files that you generate have that 
attribute?
