C. M. Sperberg-McQueen shared with us, that Mozilla Firefox browser doesn't implement the XPath namespace axis (ref, http://cmsmcq.com/mib/?p=757). CMSMcQ has encouraged us to cast a vote on Mozilla forum, to push Firefox team, to implement XPath namespace axis. I agree with CMSMcQ, and also find that XPath namespace axis is quite a critical functionality for XPath data model. This is certainly true for XPath 1.0, where namespace axis is very critical (and Mozilla, implements XPath 1.0). In XPath 2.0, namespace axis is deprecated but namespace nodes still is a core part of, XPath 2.0 data model as well.
I have already casted my vote for this with my support at, https://bugzilla.mozilla.org/show_bug.cgi?id=94270.
Other's might follow, please.
