Description nanto_vi (TOYAMA Nao) 2009-11-01 05:43:20 PST
Node.isDefaultNamespace('') and Node.isDefaultNamespcae(null) can return different values although DOM3 Core says "In programming languages where empty strings can be differentiated from null, empty strings, when given as a namespace URI, are converted to null."

To reproduce, execute the following JavaScript code:
document.implementation.createDocument(null, 'root', null).isDefaultNamespace('')

Expected: true
Actual: false

Confirmed on WebKit-r50095

Mass moving XML DOM bugs to the "DOM" Component.
