Class DummyNamespaceResolver

java.lang.Object
  net.sf.saxon.expr.instruct.DummyNamespaceResolver

All Implemented Interfaces:

Serializable, NamespaceResolver

public final class DummyNamespaceResolver
extends Object
implements Serializable, NamespaceResolver

A dummy namespace resolver used when validating QName-valued attributes written to the result tree. The namespace node might be created after the initial validation of the attribute, so in the first round of validation we only check the lexical form of the value, and we defer prefix checks until later.
