I think I should have made a clearer distinction between the three usage 
patterns I outline in the proposal -

[a]    added meta-data, as when you SchemaProcess() a root element and 
then query SchemaResults() on that element *or any child node* to get 
type or other meta-data for the node in question. This is what I regard 
as the base case, and what is outlined in the first use case.

[b]    alternative instance data, as when Default values are added - in 
this case you SchemaProcess() an element and then substitute the 
SchemaResults() from *that* element as instance data for onward 
processing, though still using usage [a] to query meta-data on this new 
instance data, and

[c]    piped processing, where the results of one type [b] processing 
step are used as input to another. The third use case is meant to 
illustrate types [b] and [c] usage patterns.

In summary, case [a], which is what I think you are asking for above, is 
in fact the basic usage, and what I meant by the first 'L' in Locally 
Linked Infosets.

Francis.
