templates sapo
I think i understand, but if you have

<xsl:template match="h3">
(...)
<h3><xsl:apply-templates/></h3>
(...)
</xsl:template>


aplyed to


<root>
<h3>
   <h3>
     (...)
   </h3>
</h3>
</root>

doesn't that falls in a kind of loop?

Or does the apply-templates only apply to the childrens of the node being
processed?
