Kirill Gavrylyuk:

You raised the following last call issue against the XML Protocol
Attachment Feature document:

  "4. Section 6: We suggest to explicitly reference the equivalence rules
  used for the URIs when the message parts are identified. (We believe
  editors meant the URI equivalence rules specified in the URI spec [3]).
  The fact that XML namespace spec uses different equivalence rules for
  namespace URIs then the original URI spec causes a confusion among
  developers on which rules to use in each case of the URIs use."

Section 6 of SOAP 1.2 Part 1 discusses uses of URIs in SOAP including 
determination of a base URI for relative URIs and URI equivalence 
rules.  We propose to resolve your issue by adding a reference to this
section to the AF document (without duplicating text between Part 1 and the 
AF specification).  The revised text reads:

  *  A mechanism by which each part is identified using one (or more) 
  URI(s), see (ref to SOAP Part 1, 6. Use of URIs in SOAP). The URI 
  scheme used MAY but need not be the same for all parts. The URI scheme 
  used for multiple identifiers of a single part MAY but need not be the 
  same.
       Note: the ability to identify a single part with multiple URIs is 
  provided because, in general, the Web architecture allows such multiple 
  names for a single resource. It is anticipated that most bindings will 
  name each part with a single URI, and through the use of base URIs, 
  provide for absolute and/or relative URI references to that URI.



We trust this satisfies the issue that was raised.  Please let us know
as soon as possible if it does not.
