I was just suggesting that there be a "xf" namespace 
such that:

  <xf:func arg="val" />    is treated as    <xsl:call-template 
                                              name="func">
                                              <xsl:with-param
                                                name="arg"
                                                select="val" />
                                            </xsl:call-template>

This would make for a very simple syntax for calling a 
template with within another template.  And this syntax
can easily be implemented using XSLT 1.0 using a stylesheet.

There are two seperate items:

  (a) making a way to define 'xpath' functions
      from within XSLT (thus it must be a function
      and support boolean, string, node-set, and
      number data types)

  (b) a less verbose call-template syntax

I'm after the latter, while it appears many on this list
are designing the former.
