[u]Query:</u>
Why the currentDate with format is not correct with current date and why such a warning message.

Well obviously the XSLT processor you are using doesn't support format-number() function, so whatever is in the date.format-date.template.xsl file isn't working, therefore your output is not correct.

Seems fairly self explanatary to me.

A quick google for "Xalan-C format-number" reveals that to enable the format-number function to work with Xalan-C you need to configure the product to use the ICU library. (If you need help with that, ask on the Xalan forums, not here!)

I expect the error occurred because the included stylesheet module date.format-date.template.xsl contains a call to format-number().
