+--org.apache.commons.betwixt.strategy.NamespacePrefixMapper
- public class NamespacePrefixMapper
- extends java.lang.Object
Maps namespace URI
's to prefixes.
When validating xml documents including namespaces,
the issue of prefixes (the short expression before the colon in a universal name)
becomes important.
DTDs are not namespace aware and so a fixed prefixed must be chosen
and used consistently.
This class is used to supply consistent, user specified prefixes.
