You can't do it well.  In the DTD you would have to allow xsl:if,
xsl:else-if and xsl:else anywhere.  DTDs don't work very well for
expressing the structure of XSL stylesheets. What's needed is a cross
between an element content model and a mixed content model, where you
have the full power of an element content model, but #PCDATA is allowed,
and whitespace is handled by applying a default white space handling
rule of ignoring whitespace-only #PCDATA chunks.

Probably true.
