Subject: RE: [ubl-lcsc] [Analysis Team] Re: Revised Model diagram

Unfortunately, that'll run afoul of the recent switch in the NDR.  Elements
are now global.  That means that if you see two elements with the same tag
name then you can count on them being of the same type.  This rule will be
enforced by schema processing and validation.

the idea of having unambiguous items makes a lot of sense with respect to
the modeling of the message structure. For the message's XML instance
however we tried so far to avoid every unnecessary overhead, especially on
item and on schedule line level. In so far I would suggest to realize the
unambigous items only as a schema type not as a tag name, e.g.

	<Item> of type "DespatchAdviceItem"

	<Item> of type "ReceiptAdviceItem"

The semantical relationship between the item and the corresponding "parent
element" in the XML instance can already be identified by the hierarchical
structure (e.g. "Item" is subelement of "DespatchAdvice" etc.).
