Hi Folks,
I've finally gotten back to trying to perform strict validation of an XML
document that has no namespace. Given the example that Geert provided below
and Mary's feedback, the following xquery is able to successfully validate
an XML document and to display the validated document (with one exception
which I will mention afterwards):
xquery version "1.0-ml";
import schema "" at "/my-schema.xsd";
declare default element namespace "";
let $node := fn:doc("/A/B/my-doc.xml")
return validate strict { $node }
where the namespace is defined in my-doc.xml as follows:
<root xsi:noNamespaceSchemaLocation="/my-schema.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
Note that the schema is located in the root of the Schema database.
The exception is that if the schema name lacks the forward slash in the xml
document as follows:
<root xsi:noNamespaceSchemaLocation="my-schema.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
then the validation proceeds without any errors being thrown but returns no
document (so I don't think validation is working in this case). I don't
know if it needs the "/" because the document is not located in the root
path of its database or if the path is required to find the schema in the
Schema database. The documents I am trying to validate do not include the
"/" path. I can always revise them, but I'm looking for a quick fix.
Thank you!
Tim Meagher

The problem is that you are declaring the namespace twice.
The correct way to do this is:
declare default element namespace "";
import schema "" at "/my-schema.xsd";
