Given a DataLink value that was inserted into column COLA of a row in table TBLA using the scalar function:
DLVALUE('http://dlfs.almaden.ibm.com/x/y/a.b','URL','A comment')
then the following function operating on that value:
DLURLPATH(COLA)
will return the value:
/x/y/****************;a.b(where **************** represents the access token)
