Hi, I am looking for a native XML DB supporting schema aware functions like let $c1 := doc("s1.xml")/s1:n1 $c1 instance of element(s1:n1,xs:string) s1.xml: <s1:n1 xmlns:s1="foo:bar" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="foo:bar test1.xsd">hello</s1:n1> s1.xsd: <?xml version="1.0" encoding="UTF-8"?> <schema targetNamespace="foo:bar" elementFormDefault="qualified" xmlns="http://www.w3.org/2001/XMLSchema"> <element name="n1" type="QName"/> </schema> Does BaseX support these schema aware functions? Thanks and best regards Malix
