Describe the bug
Based on this report:
https://www.oxygenxml.com/forum/viewtopic.php?f=1&t=25733
I'm using from Oxygen XML Editor the API "org.exist.xmldb.RemoteXPathQueryService.execute(CompiledExpression)" to run this xpath expression:

 map { 'prop1' : 'value 1', 'prop2' : 'value 2' }

which returns directly a map.

The API returns a RemoteResourceSet, I create an iterator over it, I receive a RemoteXMLResource on which I call org.exist.xmldb.RemoteXMLResource.getContent(). The returned content is an empty string.

Expected behavior
The returned content should be some serialization of a map.

To Reproduce

Use the Exist xmldb API to run an xquery like this:

map { 'prop1' : 'value 1', 'prop2' : 'value 2' }
