This is an archived snapshot of W3C's public bugzilla bug tracker, decommissioned in April 2019. Please see the home page for more details.
These tests don't use an environment containing a <collation> URI. The tests use &coll; and not &collw3c;. In collation.dtd we find: <!ENTITY collw3c "http://www.w3.org/xslts/collation/caseblind"> <!ENTITY coll "http://saxon.sf.net/collation?ignore-case=yes">
I have checked in a fix for this bug.
