RFR (JDK10/JAXP Doc-only) 8189704: broken links in the javax/xml/namespace package

[huizhe wang]

Hi,

Please review a doc-only fix for two namespace classes. The broken links 
to the Errata are removed since the reference(s) to the Errata is part 
of the Namespaces in XML specification itself. There is no need for the 
extra link(s).  Also, for NamespaceContext, the link to "Namespaces in 
XML" shall be to the specification, not the QName section, the fragment 
portion of the link, e.g. "#ns-qualnames" therefore is also removed.
