getAppStructuresByName returns null if nothing is found.

["Galt, Stuart A" <stuart.a.galt@boeing.com>]

Hello,

In the spec it says:
getAppStructuresByName
Returns the list of Application Structures whose names are given by
apsName 
in the order in which they are encountered in a preorder traversal of
the 
WebCGMPicture tree. If no such Application Structures exists, returns
null. 
Only WebCGM Application Structures may be retrieved using 
getAppStructuresByName.

I was having problems with one of my test cases and Benoit pointed out
that my problem was using the wrong name in my getAppStructuresByName()
call and was getting a null value.  Should it return null if the
application
strucutre does not exist.  Or would it be better for an empty NodeList 
to be returned?

I think that an empty list would make it easier on the script writers.

Stuart.
