(Replying to self) Dan's email bounced... I'm looking for the correct 
syntax to display a list similar to "Subject" in the metadata_edit_form I 
think this is also what Norman was after. 

i.e. I have a list of countries (a multi-valued portal_metadata element 
"Countries", filled with values -- and counterpart keyword index and 
metadata in portal_catalog) 

Changing the first line of the snippet below to

<dtml-let contentSubject=Countries 

returns a keyerror? What am I still missing here?

<dtml-let contentSubject=Subject
 allowedSubjects="portal_metadata.listAllowedSubjects( this() )"
 >
 <select name="subject:list" multiple>
 <dtml-in allowedSubjects>
 <dtml-let item=sequence-item
 sel="item in contentSubject and 'selected' or ''"
 >
 <option value="&dtml-sequence-item;"
 &dtml-sel;> &dtml-sequence-item; </option>
 </dtml-let>
 </dtml-in>
 </select>
 </dtml-let>

Ah (lightbulb switches on) I guess I'll look at this sometime in the future 
then, I don't expect topics on my site to be created all too often, this 
part can wait :) Thx!
