I want an XSL function to return one string and two integers. I know I
can write :

<xsl:function name="doc:myfunc" as="xs:string*">

</xsl:function>

and use the number() function for the 2d and 3d strings returned.
That's what I'll do if I can't do anything else, but i'm just curious
to know if something like
<xsl:function name="doc:myfunc" as="(xs:string,xs:integer,xs:integer)">
works (I tried both with and without brackets, always gets "XPST0003:
SequenceType syntax error" from Saxon)


You can't mix data types in a sequence type, so
use a more generic data type that encompasses the ones you have.

The most generic would be item() as it holds both nodes and atomic types:

<xsl:function name="doc:myfunc" as="item()*">

You can refine that to a closer encompassing data type.

I hope this helps.
