If you are a user of xmldsig XPath transforms, then this spec is for you!
"This specification defines a new XML Signature transform to facilitate the
development of efficient document subsetting technologies that interoperate
under similar performance profiles."
I haven't identified any specific groups from which we want feedback from
since we're not addresses any new requirements, we're merely improving
performance and ease of subset specification. However, comments are welcome
from all.

XML-Signature XPath Filter 2.0

Abstract
XML Signature [XML-DSig] recommends a standard means for specifying
information content to be digitally signed and for representing the
resulting digital signatures in XML. Some applications require the
ability to specify a subset of a given XML document as the information
content to be signed. The XML Signature specification meets this
requirement with the XPath transform. However, this transform can be
difficult to implement efficiently with existing technologies. This
specification defines a new XML Signature transform to facilitate the
development of efficient document subsetting technologies that
interoperate under similar performance profiles.
Status of this document
This is Last Call for the "Signature Filter Transform" Working Draft
from the IETF/W3C XML Signature Working Group (Activity Statement).
This specification defines an alternative to behavior of the XPath
transform of the XML Signature Recommendation [XML-DSig]. The goal is
to (1) more easily specify XPath transforms and (2) more efficiently
process those transforms. This specification has already received a
large amount of discussion and implementation (interop-matrix) within
the Working Group. We hope to move to and through Last Call and then
Candidate Recommendation quickly. The duration of the last call is
three weeks, closing on 11 July 2002.
The Working Group will try to use a new namespace when changes in its
syntax or processing are substantive. However, this namespace might be
reused (prior to reaching Candidate Recommendation) by subsequent
drafts in such a way as to cause instances using the namespace to
become invalid or to change in meaning or affect the operation of
existing software. Requests for a more stringent level of namespace
stability should be made to the Working Group. This version (20020620)
uses a new namespace as it contains changes that permit the efficient
combination of multiple transforms.
