How to reorder tree by member

Hi,
I'm a little new to some of the finer intricacies of XSL, and am trying to
take in the following XML information, and output it in a list, ordered by
GROUP, but so that the
GROUP name is mentioned once.

I had thought it would be a simple case of either uniquely sorting the group
text, or  using first-of-type() in some way, but I just can't seem to get
the voodoo right, or find a good example [BTW, I'm using the LotusXSL parser
if that helps]. I guess I may be easier to do it as an IDREF for the groups,
but I'm really after a solution that works with the information like this,
if one is possible.

Thanks,

Andy.


Input:
	<EMPLOYEE>
		<USER>
			<NAME>John Doe</NAME>
			<GROUP>Development</GROUP>
		</USER>
		<USER>
			<NAME>Steve Smith</NAME>
			<GROUP>Development</GROUP>
		</USER>
		<USER>
			<NAME>Jane Smith</NAME>
			<GROUP>Marketing</GROUP>
		</USER>
		<USER>
			<NAME>A. N. Other</NAME>
			<GROUP>Marketing</GROUP>
		</USER>
	<EMPLOYEE>

Output:
	Development
		John Doe
		Steve Smith
	Marketing
		Jane Smith
		A. N. Other
