EML

Some EML documents can be imbedded inside others, e.g., protocols and citations under dataset/methods. This is appropriate for some uses, but there are connections between some resources that require another type of cross link.
Example: a published citation used data from dataset.xxx.2, and should be able to include a reference to this dataset in its description. If dataset.xxx is updated to revision 3, the link between the citation and dataset.xxx.3 is not appropriate, although the relationship to rev 2 still exists.
