I cite the OASIS genericode namespace as an example of using RDDL in XHTML: http://docs.oasis-open.org/codelist/ns/genericode/1.0/ And I used the following stylesheet to help me polish the document's accuracy: http://www.CraneSoftwrights.com/resources/#showrddl Case sensitivity is implied by the Namespaces in XML specification: http://www.w3.org/TR/2006/REC-xml-names11-20060816/#NSNameComparison I can think of no guidelines for namespace components other than not implying there is a schema at the URL. Just plan ahead so that you can create a number of namespace URI strings without collisions. I regret that the OASIS policy at the release of UBL was URN-based and not URL-based, but such was the case at the time. I hope this helps. . . . . . . . . . . . . . .
