I guess that this is not so much an issue as a comment.
Dataset linkage is always the fun in this field, isn't it. What do you mean by external identifier type, is this a piece of an xref table or an argument type that would be passed to a query saying "I have one of these, please look up whatever you call it in your database for the following query"?
A good example would be an ontology term. You would have the string that encodes the ontology term and then a URL for where to go to find out more about that ontology term.
I think there is no way around providing a way to signify to users that they must look up identifiers in external databases. We are working on defining an External Identifier data type to deal with this.
