adding xlink:type attribute

Hello all,

I have been reading about namespaces in general and xlink in particular.
According to the xlink spec,

xlink:type="simple"

is required for a simple (i.e. not extended) link, which is the way 
THREDDS is using xlink.
Adding it means software that is xlink-aware (mozilla for one) will 
display links as links, though in mozilla's case, it is only apparent if 
you add a

<?xml-stylesheet type="text/css" href="threddsstyle.css" ?>

line to the thredds catalog so that mozilla actually processes the xml 
file in a standard way.

I have added it to the THREDDS catalogs I generate, with no obvious ill 
effects so far.

If there are ill effects, please let me know.

I would hope that the THREDDS standard would add this so that the 
THREDDS xml is better understood  by more software.

Benno
