Oops. Right. Thanks.

Yes. I know. But, the big question is: If ZPT doesn't care about XML (which
has been a point of discussion for 1.0), we only require 2 things of clients
like DW:

1. They should not remove end tags. If it changes <p /> into <p></p>, this
is okay. But it shouldn't remove any end tags explicitely put in by the
user. Anytime a TAL attribute is found, the element it is found in is
expected to be well formed (or at least properly closed).
2. They shouldn't touch our namespaced attribute markup. <abc
tal:xyz="something" /> shouldn't be munged.

Regarding boolean attributes, I don't think we have any semantically legal
constructs of the form tal:name="".  We have a special keyword called
'nothing' , so tal:name="" should be spelled as tal:name="nothing".
