An XSLT processor is very unlikely to do a serial search of template rules
to find the one that matches. It will typically build some kind of decision
tree or hash table at compile time. If a template rule is of the form

  <xsl:template match="some-element-name">

then it's very unlikely that it will add perceptibly to the cost of
executing xsl:apply-templates on a node that is not a <some-element-name>
element.

Of course, I'm making assumptions here about XSLT processors whose internals
are known only to the vendors.
