This is MS.NET bug note. I confirmed them with version 1.1.

In this document I refer to OASIS test suite. It is located here:
http://www.oasis-open.org/committees/documents.php?wg_abbrev=xslt

No. 0001

	position() handling in predicates is incomplete. For example,
	see foo [position() mod 1 > 0] [position() > 3] [2] result 
	(match_match19.xsl, match_match22.xsl and match_match26.xsl)

No. 0002
	Import precedence resolution on attribute sets are buggy if there are
	two imported stylesheets and both of them have identically-named
	attribute in the identically-named attribute sets. MS takes the one
	from the first stylesheet, but it must be the one from another.
	(attribset_attribset_45.xsl)

No. 0003
	http://www.w3.org/1999/11/REC-xslt-19991116-errata/ E26 says that
	attribute sets are combined before use-attribute-set is replaced with
	the actual attributes. MS does not conform to this requirement.
	(attribset_attribset42.xsl)


Notes:

1. Roman numbering

	MS.NET has "Oxford style" which for example converts 99 as
	XXXXXXXXXIX. It is not violating XSLT 1.0 spec. However, section
	7.7.1 explicitly describes 4 and 9 as iv and ix, so strict Oxford
	style violates the spec.
