The required XSLT component is xsl:template. XSLT transformations are driven by templates, which define the transformation rules that apply to matched XML nodes. A template can match a source element or be called by name, and it contains the instructions that produce the transformed output. xsl:apply-template is not the correct element name; the correct XSLT instruction is xsl:apply-templates, and it is used to invoke template processing on selected nodes. xsl:call-template calls a named template but does not by itself define the rule being executed. xsl:output controls serialization settings such as output method or encoding. For valid transformation logic, the core executable rule container is xsl:template.
