At the end of the sprint, Balazs and I discussed syntax for a few 
features that we did not know how to implement.

We suddenly recalled that CSS has stuff like the following :

border: solid 1px black;

and that those space-separated values were a solution to the features we 
wanted to implement.

I think it is the case this time as well.

I propose that we explore the thing shown below.

kss_MarshallTest-value_record: currentFormVar('arecord:record') record


This would be a non invasive zopism :

frameworks that do not pass type like Zope does would not state type and 
they would even not know...

Your opinion ?

PS: I do not have a lot of time this week to discuss more. Please hassle 
me in the coming days
