Thank you Mike
The solution using constructors worked great.

The error message is telling you that what you're passing in is an element
named images, not a document node.

as document-node()
You're passing in an element because you constructed the map entry using XML:
{$metaDatabase}.
A document node can't live inside an element, so the evaluator unwrapped it for
you. You can see this happening with a simple test.
map:map(
http://marklogic.com/xdmp/map";>
imageMetaData
{ document { '' } }
)
! map:get(., map:keys(.))
! xdmp:describe(.)
=>
text{""}
That's a text node, not a document node.
There are a couple ways to fix this. The most concise is to change the expected
parameter type:
Another approach - possibly better - is to change the way you build your map.
You're building a map using direct XML constructors, which is a little awkward
in this context and makes it impossible to include a document node. Instead you
could build the map using entry constructors and map:new(), something like this:
map:new(
(map:entry('imageMetaData', $metaInputDoc),
map:entry('metaDatabase', $metaDatabase)))
Now you have a map:map item, and its map entries can contain document nodes.
Here's a test to prove that this works:
map:new(
(map:entry('imageMetaData', document { '' }),
map:entry('metaDatabase', document { '' })))
! map:get(., map:keys(.))
! xdmp:describe(.)
=>
document{}
document{}

[MarkLogic Dev General] Sending document node as parameter to xdmp:xslt-invoke
Hi all!
I'm currently working on a xslt transform driven from xquery and have some
parameters including a document node that I want to pass to the xslt.
However I get an error whit the following code.
.
let $metaInputDoc := xdmp:eval('declare variable $metaInputPath external;
fn:doc($metaInputPath)',$evalParams,$xqueryevalOptions)
let $imageParams := map:map(
http://marklogic.com/xdmp/map";>
imageMetaData
{$metaInputDoc}
metaDatabase
{$metaDatabase}
)
(:here the problems begins:)
let $metaDocs :=
xdmp:xslt-invoke("/bilddatabas/Image_transform.xsl",$curDoc,$imageParams,{xdmp:database($metaDatabase)}
)
return $metaDocs
And the xslt params are declared as follows
http://www.w3.org/1999/XSL/Transform";
xmlns:db="http://docbook.org/ns/docbook";
xmlns:xs="http://www.w3.org/2001/XMLSchema"; version="2.0">
<-oxygen complains here
And last the error message
XDMP-AS: (err:XPTY0004) http://marklogic.com/xdmp/map";>
9789144027975/image001.eps
as document-node()
Is this that it's not possible to pass a document node as a parameter into an
xslt transform from xquery in marklogic or is it that I'm doing it wrong?
Any help is appreciated :)

Erik
