/*
 * Problem:
 *
 * I'm wondering if schemaLocation in an XML document is configurable 
 * i.e. not hardcoded in the XML instance. For example, I want to be able 
 * to do xml validation using a schema file located on our intranet, then 
 * send the xml document to another organization via HTTP. The other 
 * organization's system won't be able to access our schma file. So I 
 * would like this organization to use a copy of the schema but located 
 * in their intranet to validate the XML. (Lei Chen)
 *
 * Solution:
 *   - Use http://apache.org/xml/properties/schema/external-schemaLocation
 *     property to specify xsd file! (Maik Weber)
 *
 * Resources:
 * [1] Xerces 1.4.1 docs on properties
 *     C:\Program Files\xerces-1_4_1\docs\html\properties.html
