Hi Folks,

Ken Holman sent me some corrections and additions. Here's the updated version. Thanks Ken!   /Roger


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
