purgeUnusedNamespaceDeclarations

protected static void purgeUnusedNamespaceDeclarations(org.jdom2.Element root)

Purging unused declarations is less optimal, performance-wise, than never adding them in the first place. So, we should still ask the ROME guys to fix their code (not adding dozens of unnecessary module declarations). Having said that: purging them here, before XML generation, is more efficient than parsing and re-molding the XML after ROME generates it.

Note that the calling app could still add declarations/modules to the Feed tree after this. Which is fine. But those modules are then responsible for crawling to the root of the tree, at generate() time, to make sure their namespace declarations are present.
