Subject: [wss-comment] Input format to Transform

Comments on SwA CD [1]

The Attachment-Complete Transform needs to operate on attachment content
and MIME Headers. Currently, the SwA draft [1] does not identify how the
such dereferenced information (both content and MIME header information)
needs to be provided to the transform as input.

The xml-dsig spec [2] says that input to a transform should be a nodeset
or octet-stream and all other information needs to be provided as
transformation parameters.

Quoting the relevant piece from xml-dsig core [2] (section

'Some Transforms may require explicit MIME type, charset (IANA
registered "character set"), or other such information concerning the
data they are receiving from an earlier Transform or the source data,
although no Transform algorithm specified in this document needs such
explicit information. Such data characteristics are provided as
parameters to the Transform algorithm and should be described in the
specification for the algorithm.'

There should be a  standard input format to the Attachment-Complete
