I don't like to implement something different then ITerms
defined in zope.app.form. I'm fine if we remove the request
as an adapter discriminator.

ITerms could adapt only the ISource as a single object.

The important thing is. zope.schema defines ITerm and 
ITitledTokenizedTerm and offers support wihthin the 
SimpleTerm for implement simple usable components
if it comes to using widgets.

A widget needs most the time a label for represent
a token and needs a HTML aware token id.

This ITerm is not a requirement for make an ISource
implementation usable. It's just one concept, but this
one is accepted and used in zope e.g. zope.app.security.

Right now ITerms defined in zope.app.form brings in
some bad dependencies to zope.app.form. e.g. in 
zope.app.security and makes it impossible to use it in 
z3c.form. 

That's all I like to solve.


My  Fazit is,
all of you agree on the ITerms pattern and you are
using that pattern within zc.sourcefactory.

Can you explain why this ITerms interface should be 
a part of a specific form framework like zope.app.form?
