How to count number of "concat()" args in XPath expression

I wanted to know the (huge) argument number count of a "concat()" call in
a customer stylesheet.

Since I did not want to write my own XPath expression parser I made use of
the "Too many arguments to user-created function" error of DataPowwer XSLT
Processor. As can be seen below Saxon 6.5.5 (XSLT 1.0) processor can be
used for that, too.

I created a small stylesheet with a "func:concat()" user defined function.
In that I inserted 900 parameters created by
$ for((p=100; p<1000; ++p)) do echo "<xsl:param name=\"$p\"/>"; done

Finally I modified "concat()" call to "func:concat()".

Binary search and recompile finally identified the argument count 814(!).

My question is, whether determining the argument count can be achieved
easier (with any tool/language). Can XSLT 2.0 (3.0) help here?

<xsl:stylesheet version="1.0"
  <func:function name="func:concat">
<xsl:param name="a100"/>
<xsl:param name="a101"/>
<xsl:param name="a911"/>
<xsl:param name="a912"/>
<!--<xsl:param name="a913"/>-->
    <func:result select="$a912"/>
  <xsl:template match="/">
                <xsl:value-of select="func:concat('SELECT',
