 In addressing issue 9 I started to review WS-I Basic Security Profile

WS-I BSP addresses Transforms as one unit and references a number of
specifications from  the W3C in specifying how to form the transform
structures, but these are based on XML-DSIG 1.0.   In DSIG 1.1
(http://www.w3.org/TR/2009/WD-xmldsig-simplify-20090226/)  transforms
are broken up into three sections "Selection, Transforms and

Will this change impact WS-I BSP?  The BSP is clear on which and what
order of elements to include. Is it that WS-I BSP will still need to use
XMLdsig 1.0 because we are breaking apart transforms??

For C14N WS-I BSP  says "Any CANONICALIZATION_METHOD Algorithm attribute
MUST have a value of "http://www.w3.org/2001/10/xml-exc-c14n#"
indicating that it uses Exclusive C14N without comments for
canonicalization. " 

I do not see that our work will impact this aspect, 
http://www.w3.org/2001/10/xml-exc-c14n#  will still be available
