This sort of thing is, and more or less always has been, a shortcoming 
with the Mathematica documentation -- the lack of complete information 
about admissible values.

It think the Version 6 reference pages for named objects do a better job 
at this than was done in earlier version, namely, in the initial 
specification of syntax and the More Information section that follows 
it.  But still, as for earlier versions, in many cases the totality of 
admissible values is only suggested, through the examples. At least we 
often have more examples than before, with their neat division into 
Basic Examples, Scope, Options, etc.

I can see at least three reasons for why complete specifications for 
admissible values are not available:  (1) it would be a herculean 
undertaking; (2) the docs would become unmanageably huge; (3) for the 
newest functionalities, there has not been sufficient time to do it.

I can imagine how unhappy many of us would have been had the release of 
Mathematica 6 been delayed for many more months while such "complete" 
documentation was completed.
