It's presumably failing because you declared the type on xsl:param not to
accept an empty sequence. For example if you write <xsl:param name="p"
as="xs:string"/> then an empty sequence will not be accepted. If you change
it to <xsl:param name="p" as="xs:string?"/> then an empty sequence is OK.

Subject: [xsl] Possible to pass 'empty sequence' to function?
Hi,
Using Saxon 8 and XSLT 2.0, I have some functions defined in my
stylesheet using <xsl:function/>.
These functions usually have parameters to pass it an element. The
trasnformation fails when I pass an empty sequence as a parameter.
Since I may call a particular function as part of my xpath from many
parts of the stylesheet, I would much rather the function handle null
elements rather than doing it at each place I call it.
Is there no way to allow my function to accept empty sequence
parameters??
Thanks!
