@acarey this is a good idea and should be feasable to some extent.
The DQL docs mostly predate Slash and there was no need to make examples with type dotted predicates. I believe this is covered elsewhere in the docs but not sure exactly where atm without searching.
Happens to me all the time as well!
The period is rdf syntax indicating end of statement. It is possible to have more than a single value in rdf as is used in the upcoming namespace implementation where the 4th item in the rdf will be the namespace.
