[ubl-lcsc] Re: Customizing UBL

[Tim McGrath <tmcgrath@portcomm.com.au>]

Can you clarify a few technical points for me?

1. you state that 'UBL uses explicit type defeintions for all elements' 
(page 3).  yet when i look at a schema i see things like 'Street' as a 
'TextType'.  did you mean each element should have its own type e.g. 
'Street' should be 'StreetType'?  In your example of refinement you show 
'Address' being restricted.  'Address' is an aggregate and therefore a 
complexType with its own 'AddressType'.  What if I wanted to restrict 
'Street'?  Can i do that?

2. am i correct in thinking the concept of ur-type was introduced 
because XSD does not allow certain derivations (such as making mandatory 
fields optional)?  Are there other reasons for needed them?
