So in 3.5.1 (Admin guide, section 9.2.1) you can grant users rights to
one of 6 attributes, and if they get read/write access they can do
certain tasks.

The one I am interested in is DirXML-AccessManage for now.

The schema definition in my tree is a bit odd to my eye. There is no
class associated with this attribute, and the syntax is Unknown...

Is that normal? I do not think so, but do not have a spare test tree to
look at and see if this is the case.

could someone look at theirs and let me know?
