I think we should add this for Zope 2.8. See also discussion

"""
Request:
Could there be a modifier to tal:attributes, much like 'structure' when applied to tal:replace that prevents ZPT from escaping or otherwise fixing the data being applied to that attribute?
"""

This has been discussed in the past and there was no common agreement to add something like that.

Background:
Sometimes we need to generate non-standard attributes, which while not being valid XML has some practical value when integrating Zope applications with other systems. 
 
I am working on an application part-written in Zope that makes content for a mailing system to re-distribute. The mailing system takes HTML documents with some embedded TCL. I would like to be able to generate all of this using Zope and ZPT - the problem is the embedded TCL requires characters that ZPT will not allow in attributes.

Rationale:
Some other applications *REQUIRE* HTML-like input formats, despite not being valid XML, it would be great if these with the ZPT I know and love.
 
Example - How I am generating <a> tags:
<a href="webTi.html" tal:attributes="href python:here.pyscripts.uri(content_object)">click me</a>
 
Example - an attribute I need to create:
<a href="%%track http://zope.hobo.hhub/demo/club_six/section?obj=section&id=6%20-name%20"Resistance%20training"%%">click me</a>
 
Example - What actually happens:
<a href=&quot;%%track http://zope.hobo.hhub/demo/club_six/section?obj=section&id=6%20-name%20"Resistance%20training&quot;%%">
 
Explaination:
ZPT is smart enough to know that an attribute should never contain a " (quote-mark) character, so it has tried to escape it to preserve sanity... however in this case it has done the wrong thing, I actually wanted the EXACT output of the function - no matter how bizzare it looks.
 
Request:
Could there be a modifier to tal:attributes, much like 'structure' when applied to tal:replace that prevents ZPT from escaping or otherwise fixing the data being applied to that attribute?
