Hi Florent, Thank you!
Using map:entry solved it and goes with my intentions. Also thanks for the great explanation it’s obvious why map:map doesn’t work when its explained well.

The following returns true (that is, it stores a document node as the value of the key "key" in the map): let $doc := document { <foobar/> } let $map := map:entry('key', $doc) return map:get($map, 'key') instance of document-node() So what is the difference with the following, which stores an element node instead? let $doc := document { <foobar/> } let $map := map:map( <map:map xmlns:map='http://marklogic.com/xdmp/map'> <map:entry> <map:key>key</map:key> <map:value>{ $doc }</map:value> </map:entry> </map:map>) return map:get($map, 'key') instance of element() The difference is that the above first copy the document node to an XML tree. A document node added to an element is just "ignored", its children get copied directly, as per the XDM recommendation. This XML tree is used as an XML representation of a map, and "deserialized". What is in the element map:value *IS* an element node at this point, so ends up as such in the map. This might be more clear if we get rid of all the map machinery: let $doc := document { <foobar/> } let $elem := <value>{ $doc }</value> return $elem/node() instance of element() The value of $elem in this last code is the following (which makes sense, right?, what else could it be?): <value> <foobar/> </value> Regards, -- Florent Georges H2O Consulting http://h2o.consulting/ On 15 February 2017 at 11:37, Erik Zander wrote: Hi All, I did iron out why I got errors, now I could use some help finding the best solution to it. The error is that I have code like …… let $evalParams := map:map( <map:map xmlns:map='http://marklogic.com/xdmp/map'> <map:entry> <map:key>document</map:key> <map:value>{$doc}</map:value> </map:entry> </map:map>) let $resultDocument := xdmp:eval($transformCode, $evalParams) where in the $transform code it checks for a document-node declare variable $document as document-node() external; To my understanding this has to do with the map:map structure. But is there a good way of going around it. I could use xdmp:unqote but it feels a bit messy. I could also put into the database but doing document inserts and deletions just for that feels like a bit much overhead. Any thoughts on this is greatly appreciated.
