[Dennis Knochenwefel <dennis.knochenwefel@xxxxxxxxxx>]

Public bug reported:

It should be possible to validate xdm instances against schemas which
are stored in collections or dynamically created. Therefore, a mechanism
is needed to tell the resolver before compiling and XQXQ module how to
find these schemas.

This could be implemented using HOFs.

Example:

declare function schema-uri-resolver($namespace as xs:string, $at-hints as xs:string*) as element(xs:schema)? {
    (: create/fetch xml schema :)
    xqddf:collection(...)//xs:schema[@targetNamespace=$namespace]
};

let $module := xqxq:prepare-main-module("import schema namespace test = 'http://test'; validate { <test:test /> }", schema-uri-resolver#2 )
return
   xqxq:evaluate($module)
