Well, you can access these properties/objects from DTML/Python. Not from

Well, because of the implementation details, it is not possible to allow
certain ids (things that start with '_' or 'aq_', etc.).
Why % is not allowed I can only guess at, but I'd assume that the
authors tried to get "sane" ids. It's a bit like the Unix Filesystem. By
definition it allows all characters except '\0' and '/'. Still it's
rather stupid and inconvienent to use exotic characters.
By the way, you can look
Zope/lib/python/OFS/ObjectManager.py:checkValidId (line 49) to see what
is allowed and what not.
