Personally, it would save me allocating a collection to collect the ESIS
style pre-element attributes for Aelfred, so that would be nice. I am
ultimately trying to call into a very similar interface:
Object createObjectFromName_parameters(String recipeName,
Where the parameters are just a bit more general in type than attributes.
A mild question would be: are you planning on being able to modify the
Dictionary after you have given it out, or can the client assume it is a
constant after the startElement?

Just a heads-up in case anyone doesn't know. In JDK 1.2, Hashtable is
NOTE: This class is obsolete. New implementations should implement
the Map interface, rather than extending this class.
The problem with Hashtable is that it is an abstract class instead of an
interface so although you can have different implementations they are
still pretty restricted in their implementation approach. This has been a
known problem for a long-long time, and the 1.2 collections are finally
interface based. The basic 'get', 'put' operations for Map are the same
though, so it is just a type-ing problem.
Not that this should weigh very heavily if you are trying to support
1.0 and 1.1 based browsers, but I suspect the 1.2 release will be migrated
to pretty rapidly (in the Spring->Summer).
