An idea which I think has been tossed around but rejected is to wrap
$_PSL lookups is a pslConfig() function.  pslConfig("resources.$urn") or
whatever could parse the string, check for existence of the keys and
levels of the multi-dimensional array, and return FALSE if it there's no
value without a warning (or maybe just a PSL-level warning that would go
away with $_PSL['debug'] off).  

Pros:

1.  No more global'ing $_PSL
2.  Can munge keys to map one level of $_PSL to another virtually
3.  More control of errors/warnings (as above)

Cons:

1.  Adds spatial complexity
2.  Probably adds time, too.  Joe says, "Remember: PHP is a scripted
interpreted language." :-P
