Since the structured element syntax already exists, wouldn't it make
more sense for an attribute to _reference_ a hierarchy of attributes,
expressed in element syntax, elsewhere in the document? Given your

I would do it like this:

 <person> age='49' name-ref='xqz4834'>
   <children ...>
   <name ID='xqz4834'>

No new syntax required.
