Does anyone know the syntax for an out-of-declaration template method in a template class.

Be forewarned: This question seems way more obvious than it actually is.
I'd like to write a template that can accept any concrete class or template class as a template parameter. This might seem useless because without knowing whether the passed in T...

Try using this (off the top of my head):
<xsl:call-template name="button"> <xsl:with-param-template>

What should getMax(1, '2'); return? An int, or a char? Think about it :)
You could write:
