eml packaging

[Chad Berkley]

Hi,

I just checked in a bunch of changes to eml.  namely, I added the
references element and an id attribute to each module for packaging
purposes.  I have not added inlined elements for direct nesting (i.e. an
attribute typed tag in eml-entity).  I will probably attempt this feat
tomorrow.  Please take a look at what I have done and send me any
feedback that you may have.

thanks,
chad
