segmentedlists

Do anyone have any XSLs trick for segmentedlists?  I would like each 
group to be delimited by a horizontal rule or some kind of separation.

i.e.  I get

Attribute: cginewfrmok
Value:
Constraint:
Explanation: Message to be displayed on a separate page whenever an
operation was successful. Used
whenever cgirefreshform is NO.
Attribute: cgirefreshok
Value:
Constraint:
Explanation: Message to be displayed on an input form when an update is
successful. Used whenever
cgirefreshform is YES.
Attribute: cgirefresherr
Value:
Constraint:

supplied value is invalid. Used
whenever cgirefreshform is YES.
Attribute: emailalerts
Value: YES
Constraint: ^YES$|^NO$

where I would like
