Each of the XSD's referenced in the I-D includes a set of IANA URI
requests for both urn:ietf:params:xml:ns (e.g.
urn:ietf:params:xml:ns:rdeCsv-1.0) and urn:ietf:params:xml:schema (e.g.
urn:ietf:params:xml:schema:rdeCsv-1.0).  The  urn:ietf:params:xml:schema
URI's are used to register the schemas and the urn:ietf:params:xml:ns
URI's are used within the XML documents that use that schema.  The field
definitions for the CSV model within the XML manifest file follow the same
convention that is used for the XML model, where there is a schema that
contains the definitions and a namespace URI that is used within the XML
manifest file.  In the case of the CSV model, the fields define the format
of the CSV files that would be used by a CSV validator.  There is a level
of indirection with the fields, since they are directly validated using an
XML parser in the XML manifest file and they include a type attribute,
with a XSD type value, that is validated by a CSV validator in the
referenced CSV files.   I don't believe there is any substantial
difference between the XML and CSV models when it comes to the IANA URI
requests.  Let me know if I'm missing something from your question.
