I liked your suggestion of using a dash in the attribute name, so I
changed my attributes to 'show-container' and 'container-name', which
will avoid the problem of matching on an object method.
However, this caused the $(form).select('[show-container]') selector
to throw an error in FF. Prototype didn't like me using a dash, and
instead of using the 'attrPresence' xpath selector it used 'attr',
because the 'attrPresence' pattern didn't include a dash but the
'attr' pattern did.
Here's a patch that fixes it for me (against the 1.6.0 release):
