Sorry if this is obvious, but at least neither ZopeFind nor 
locked_in_version() seem to be mentioned anywhere in zope's (2.3.3) online
docu, so I thought I might post it:

<dtml-in "ZopeFind(PARENTS[-1],search_sub=1,obj_expr='locked_in_version()')">
<LI>found <dtml-var title_or_id html_quote> in Version <dtml-var locked_in_version>
</dtml-in>

Hehe, I feel with you, looking at how versions work takes one straight to
Filestorage.commitVersion and some very low level code.

The question is if this is worth the effort, in the light of the
new versioning discussion. The weaknesses of the current implementation
of versioning puts some pressure to create something new IMO.
