XSV potential issue

To whom it may concern,

I was using the XSV utility today, 
(http://www.w3.org/2001/03/webdata/xsv works great! thanks) and saw that 
there was no problems in importing any file on the server within my schema.

Ex: try validating this:

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:blah="ns" 
elementFormDefault="qualified" attributeFormDefault="unqualified">
    <xs:import namespace="blah" schemaLocation="/etc/passwd"/>
</xs:schema>

You'll get errors, of course since /etc/passwd is not valid XML, but the 
fact that the XSV server has access to it is a potential danger.

Thought you might like to know,
