[XML-DEV Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] RE: Two quick questions regarding restriction in XML Schema
 As for the question on using block for restriction which I assume means using the block attribute on a complexType definition, the answer is that you'd block restriction to prevent types derived by restriction from replacing the content model of base types in an instance document. This is also described in the XML Schema Primer in http://www.w3.org/TR/xmlschema-0/#ref28 -- PITHY WORDS OF WISDOM Experience is something you don't get until just after you need it.
