Comment 6 for bug 143100

Uploaded: xmltools-fixes-1.diff

after some tests with plain zope i discovered a couple of issues with this patch. I managed to fix most of them, and even figured out the reasons for del_attr and remap methods.

Attached is a patch for this stuff to the current zope 2.7 cvs branch.

One thing needs more attention .. see issue #1561 at http://zope.org/Collectors/Zope/1561
