Mike - the chain can be arbitrarily deep because of simple type inheritance. Any DFDL processor / editor will have to be clever enough to keep track of the xsd where a given property value was sourced from. Alan - some more comments, to get wording clear and ensure that all cases are covered.

My comments added plus fixes to a couple typos. One item of substance. Suppose schema 1 contains an element reference to an element declaration in schema 2, which references a simple type defined in schema 3. Then defaults for that type can come from 3 different places. Schema 3's defaults have priority over schema 2's defaults, which have priority over schema 1's defaults. Local property annotations can similarly come from all 3 places and must be non-overlapping/disjoint over all 3. This 3-deep chain may go unnoticed.

I have also updated and extended Suman's examples. Note that he dfdl properties aren't necessarily correct for the construct and are only used to indicate where they came from. I have not yet extended to multiple schema.
