Re: [xml-dev] xquery and xsl

Robert,

I'd like to point out an XQuery 1.1 requirement (see http://www.w3.org/TR/xquery-11-requirements/) that bears on half of this question:

2.3.21 Invocation of external functionality

XQuery 1.1 MAY provide a normative way to invoke external functions and modules that are not implemented in XQuery, such as functions defined as web services or XSLT functions and templates.

Admittedly, that's a MAY and not a SHOULD or MUST, but one might not be surprised if the topic were to be discussed by the XML Query WG and/or the XSL WG ;^)

Hope this helps,
   Jim

Hi,

What are the impediments to using the same internal tree for both XQuery
and XSL? Do the respective processors require different types of trees?

Wouldn't it be lovely if you could do:

import module namespace xsl=" http://www.w3.org/1999/XSL/Transform" at
"view.xsl";

and then use:

xsl:apply-templates(nodes [, "some-mode", ((param1=x), (param2=y))])

Similary in XSL:

<xsl:import href="controller.xq"/>

and call out to XQuery functions.

Will the two ever be able to couple or are their interfacing parts
incompatible?

best,
-Rob
