When taking on this role, it is advisable to have all one's ducks in a row.

So far so good.

Not so.  The [namespace attributes] property is, indeed, what you
refer to as a "namespace declarations" property; what you call the
"namespaces" property, properly named [in-scope namespaces], is
fully redundant to it.  Both properties exist in element info items
in order to partly reconcile the conflicting models of DOM and XPath.

It's true that DOM's concerns are not fully represented, although an
Infoset-based DOM (one that discards entity and CDATA boundaries) is
quite possible and even common.

Or even as an opponent.
