Why? :-(
Why not? It is quite flexible that way.
If you want to have parameters passed to the transformation to be
accessed from within the initial template to be executed, then have
the default values of the initial template use the global values:
<xsl:param name="global-command-line"/>
<xsl:template match="/">
<xsl:param name="initial" select="$global-command-line"/>
...$initial...
</xsl:template>
Because local variables shadow global variables you could have the
following if you plan to invoke the initial template a number of
times in the transform:
<xsl:param name="x"/>
<xsl:template match="/">
<xsl:param name="x" select="$x"/>
...$x...
</xsl:template>
Since global variables are visible to all templates, if you are only
ever invoking the initial template once, then you don't need the
parameter in the template because the global parameter is visible:
<xsl:param name="x"/>
<xsl:template match="/">
...$x...
</xsl:template>
I think this flexibility is quite important.
In my XSLStyle documentation methodology for XSLT stylesheets I have
a template rule for the root node that has parameters initialized
when first invoked from the command line but passed with new values
when the same template rule is invoked later in the transformation.
Can you express what concerns you about not having them passed?
I hope this helps.
