Hudson commented on AXIOM-372: ------------------------------ Integrated in ws-axiom-trunk #443 (See [https://builds.apache.org/job/ws-axiom-trunk/443/]) AXIOM-372: Started to add a section about illegal namespace declarations to the user guide (not yet finished). veithen : Files : * /webservices/commons/trunk/modules/axiom/src/docbkx/userguide.xml > Axiom should reject attempts to create illegal namespace declarations > --------------------------------------------------------------------- > > Key: AXIOM-372 > URL: https://issues.apache.org/jira/browse/AXIOM-372 > Project: Axiom > Issue Type: Bug > Components: API, DOOM, LLOM > Affects Versions: 1.2.12 > Reporter: Andreas Veithen > Assignee: Andreas Veithen > Priority: Minor > > According to the Namespaces in XML 1.0 (Second Edition) specification, it is > illegal to bind a namespace prefix to the empty namespace URI. Only the > default namespace can have an empty URI: > "[Definition: If the attribute name matches PrefixedAttName, then the NCName > gives the namespace prefix, used to associate element and attribute names > with the namespace name in the attribute value in the scope of the element to > which the declaration is attached. In such declarations, the namespace name > may not be empty. ]" > (Note that this constraint was dropped in the Namespaces in XML 1.1 > specification) > OMElement#declareNamespace doesn't enforce this constraint and namespace > declarations that violate this requirement are silently dropped during > serialization (by code in OMSerializerUtil#isAssociated). This behavior is > problematic because it may result in subtle issues such as unbound namespace > prefixes. > The serialization code should throw an exception if the object model contains > an invalid namespace declaration. We should also make sure that Axiom itself > never generates such invalid namespace declarations. Indeed, the code in > OMSerializerUtil#isAssociated has the following comment: > "Cannot associate a prefix with an unqualifed name. However sometimes axiom > creates a fake prefix name if xmns="" is not in effect." > If this is true, then Axiom needs to be fixed. -- This message is automatically generated by JIRA.
