-------------------------------
Attachment: Betwixt-67-proposed.patch
Proposed patch
> Betwixt does not correctly implement namespace scoping
> ------------------------------------------------------
>
> Key: BETWIXT-67
> URL: https://issues.apache.org/jira/browse/BETWIXT-67
> Project: Commons Betwixt
> Issue Type: Bug
> Reporter: Nicholas W.

> According to: http://www.w3.org/TR/xml-names/#scoping
> The scope of a namespace declaration declaring a prefix extends from the
> beginning of the start-tag in which it appears to the end of the
> corresponding end-tag, excluding the scope of any inner declarations with the
> same NSAttName part. In the case of an empty tag, the scope is the tag itself.
> Such a namespace declaration applies to all element and attribute names
> within its scope whose prefix matches that specified in the declaration.
> Namespace declarations are handled in the class AbstractBeanWriter in method
> addNamespaceDeclarations
> Each new namespace declaration is added to namespacesDeclared and written out
> to the attributes of an element just once. The declaration is made just once
> in any one object as it is written out. The result is:
> Using a dot betwixt file like this:
> <?xml version="1.0"?>
> <info primitiveTypes="element">
> <element name="dc" uri="http://www.openarchives.org/OAI/2.0/oai_dc/";>
> <element name="title" property="title"
> uri="http://purl.org/dc/elements/1.1/"/>
> <element name="creator" property="creator"
> uri="http://purl.org/dc/elements/1.1/"/>
> <element name="publisher" property="publisher"
> uri="http://purl.org/dc/elements/1.1/"/>
> <element name="description" property="description"
> uri="http://purl.org/dc/elements/1.1/"/>
> <element name="identifier" property="identifier"
> uri="http://purl.org/dc/elements/1.1/"/>
> <element name="subject" property="subject"
> uri="http://purl.org/dc/elements/1.1/"/>
> </element>
> </info>
> And with the beanwriter having extra configuration of the
> NamespacePrefixMapper like this:
> prefixMapper.setPrefix("http://purl.org/dc/elements/1.1/";, "dc");
> prefixMapper.setPrefix("http://www.openarchives.org/OAI/2.0/oai_dc/";,
> "oai_dc");
> The XML generated is like this:
> <oai_dc:dc xmlns:oai_dc="http://www.openarchives.org/OAI/2.0/oai_dc/";>
> <dc:title xmlns:dc="http://purl.org/dc/elements/1.1/";>Sample
> Title</dc:title>
> <dc:creator>Sample Creator</dc:creator>
> <dc:publisher>Sample Publisher</dc:publisher>
> <dc:description>Sample Description</dc:description>
> <dc:identifier>Sample Identifier</dc:identifier>
> <dc:subject>Sample Subject</dc:subject>
> </oai_dc:dc>
> Which is wrong. The namespace declaration should be in the parent element, or
> repeated in all the child elements.
