Parsers can use dictionaries to report the attributes, which are more
efficient to access when given a key. Not sure whether this is a
processing advantage on the parser or on the application side, but it
should allow for faster overall processing.

Now, parsers could preserve the original order side-by-side with the
dictionary. In that case, not preserving the order simplifies the
implementation of the parser. Ordered dictionaries with efficient
lookup and insertion are rarely found as predefined types.
