XSLT » xsl:call-template » name="qname"

The mandatory name attribute is the unique qname of the template that you wish to invoke. A qname is a qualified name that is composed of an optional namespace prefix, a colon which is only present if there is a prefix, and a mandatory XML name (for example, xsl:zipcode or zipcode). This name must match the name used by the name attribute of the xsl:template element that was used originally to create the template.
