[Zope] Expression syntax for sort= attribute in <dtml-in ..> tag.

[Agnieszka Karpierz]

It's very, very...  great news that Ross Lazarus's multikey
sort patch for dtml-in tag is included in current Zope CVS
and will be included in Zope 2.2.

<dtml in "foo" sort=akey,anotherkey>

But for me one important think is very missed.
Possibillity of use expression syntax for sort= attribute.

Maybe syntax:
<dtml in "foo" sort="expression_which_ruturns_sort_keys">
would be possible ?

eg.
<dtml in "foo" sort="foo()">
where foo() will returns appropriate Python string
eq. 'firstname,surname,height, width,weight'  :)

I hate constructions like this:

<dtml-if something>
  <dtml in "foo" sort=key1,key2,key3>
<dtml-elif something>
  <dtml in "foo" sort=key1,key3,key2>
<dtml-elif something>
  <dtml in "foo" sort=key2,key1,key3>
<dtml-elif something>
  <dtml in "foo" sort=key2,key3,key1>
<dtml-elif something>
  <dtml in "foo" sort=key3,key1,key2>
<dtml-else>
  <dtml in "foo" sort=key3,key2,key1>

...

</dtml-in>

What we think about ?.
