           Summary: [xslt30]Example in

                    unctions defines parameter named "input", explaining

  Target Milestone: ---

While exploring streamable stylesheet functions with Saxon 9.8 I found that the
example "An absorbing stylesheet function" in
https://www.w3.org/TR/xslt-30/#streamable-stylesheet-functions has the code

<xsl:function name="f:count-descendants" as="xs:integer"
streamability="absorbing">
  <xsl:param name="input" as="node()*"/>
  <xsl:sequence select="count($input//*)"/>
</xsl:function>  

so it defines the argument of the function with the name "input", however the
explaining text then says "The effect of the rules is that a call to this
function is guaranteed-streamable provided that the sequence supplied as the
value of the $nodes argument is motionless or consuming, and is either grounded
or striding.", that is, it uses the name "nodes" and not the name "input".

So the text and the code are inconsistent as far as the argument name is
concerned.
