xpath is only used in the query section. whenever you use xpath
for querying the repository you use an @
there are probably no examples that refer to using a property in xpath=20
without an @.
(or can point out an example in the spec?)

a "content repository path" on the other hand which is used thoughout=20
the entire api to identify a single item in the content repository has very=
=20
different characteristics than xpath.

the repository path is comparable to a filesystem path, in which a node cou=
ld
be looked at as a folder and property could be looked at as a file.
