  I guess you are confused works perfectly:

paphio:~/XML -> cat test.xml
<?xml version="1.0" encoding="UTF-8"?>                                          
<Element1 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";                 
xsi:schemaLocation="http://www.mypage.com/users/app/cfg D:\usercfg.xsd">        
    <Element2 atrr1="true">                                                     
    </Element2>                                                                 
</Element1>
paphio:~/XML -> xmllint --shell test.xml
/ > xpath //Element1
Object is a Node Set :
Set contains 1 nodes:
1  ELEMENT Element1
    namespace xsi href=http://www.w3.org/2001/XMLSchema-instanc...
    ATTRIBUTE schemaLocation
      TEXT
        content=http://www.mypage.com/users/app/cfg D:\u...

  XPath in libxml2 doesn't care at all about any XSD.
