Updates this MetaData with the MetaData given as argument.
Updates this MetaData with the MetaData given as argument. All attributes that occur in updates are part of the resulting MetaData. If an attribute occurs in both this instance and updates, only the one in updates is part of the result (avoiding duplicates). For prefixed attributes, namespaces are resolved using the given scope, which defaults to TopScope.
MetaData with new and updated attributes
a new MetaData instance that contains old, new and updated attributes
gets attribute value of qualified (prefixed) attribute with given key

We insist we're only equal to other xml.Equality implementors,
which heads off a lot of inconsistency up front.

It's be nice to make these final, but there are probably people out there subclassing the XML types, especially when it comes to equals.
It's be nice to make these final, but there are probably people out there subclassing the XML types, especially when it comes to equals. However WE at least can pretend they are final since clearly individual classes cannot be trusted to maintain a semblance of order.

(Changed in version 2.9.0) The behavior of scanRight has changed. The previous behavior can be reproduced with scanRight.reverse.
(Changed in version 2.9.0) transpose throws an IllegalArgumentException if collections are not uniformly sized.
