[wsrp] [errata #13] Extensions IDL

Comment: 

13. 4/30/03 (Yossi Tamari) 

Change definition of the Extension type: 

Document: Spec 

Section: 5.1.1 

Old Text: [O] Object        
        any[]

New Text: [O] Object        
        any

Reason: The definition here is of a single Extension
field, not of the array. Anywhere else in the spec we use an array of Extension
([O] Extension extensions[]). This also matches our wsrp_v1_types.xsd better.
