[XML-DEV Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] Help with Namespace Defaulting
Hello,
Can I define xmlns = "....." as a fixed attribute of an
element?
Suppose I have Person_Data (PD) and Book (BK), both of which would
like to use an element called NAME. To keep the XML Elements unique,
I could use namespaces to keep PD:NAME distinct from BK:NAME.
MY QUESTION:
Can I use NAMESPACE defaulting via a fixed xmlns attribute
(as seen in the second example) to get rid of most of my namespace
prefixes?
=======================: With Namespaces :======================

<!ELEMENT PD:PERSON_DATA ( PD:NAME PD:AGE )/>
<!ELEMENT PD:NAME (PN:FIRST PN:LAST) />
<!ELEMENT PN:FIRST (#pcdata) />
<!ELEMENT PN:LAST (#pcdata) />
