There are some fundamental problems in your stylesheet, plus your 
question is not quite clear.

I'm lost as to which groupings you need and which you do not.  Could 
you please show an example of what you want output from the data 
above, rather than showing us the stylesheet.  That shows us what 
doesn't work, not what you want.

It is dangerous to use "/text()" in the above because of mixed 
content.  It is sufficient to say "department" because the text value 
of an element is the concatenation of the descendant text nodes.

Your escaping of angle brackets in an attribute achieves 
nothing.  There is no such thing as element markup in an attribute 
string.  Use an attribute value template to do "value-of" in an attribute:

   <a id="{current-grouping-key()}">

What do you mean by a "group name"?  If you mean the current grouping 
key, then perhaps the above is all you need.

Remember also that you always get a group even if the count of 
members of the group is one.  If you don't want to do something if 
there is only one member of the group, then you'll have to check the 
count of the current group to determine that.

I hope this helps.
