One clarification. By this statement:

    All the XPath functions

I mean all the XPath functions that I list below (doc, unparsed-text, etc)

Thanks Martin Honnen for catching this!

Subject: The use of URLs in the XML technologies to reference external resources

Hi Folks,

The XML technologies use URLs to reference external resources. For example, XML Schema uses a URL in the <xs:include> and <xs:import> elements to reference other XML Schema documents.

The below list shows several XML technologies  and where they use URLs. Please let me know if I have missed any place where URLs are used in these technologies to reference external resources.  /Roger

-----------------------------------------
XML
-----------------------------------------

1. The <!ENTITY> external entity

2. The SYSTEM url in a <!DOCTYPE> declaration


-----------------------------------------
XML Schema
-----------------------------------------

1. The <xs:include> element

2. The <xs:import> element

3. The <xs:redefine> element

4. The xsi:schemaLocation attribute

5. The xsi:noNamespaceSchemaLocation attribute


-----------------------------------------
XSLT
-----------------------------------------

1. The document() function

2. The <xsl:include> element

3. The <xsl:import> element

4. <?xml-stylesheet> PI

5. The <xsl:import-schema> element

6. All the XPath functions


-----------------------------------------
