[tdwg-content] Idea for Discussion, Differentiating between "type's" of identifiers

There were a few goals in mind when I thought of this pattern.

1) It makes it clear to processing services how to resolve the entity
2) It makes it more clear to data submitters what should go in that field
3) It allows end users who want to use the LSID system to do so without
breaking non LSID aware systems.

The use of LSID makes it clear that this should be resolved using a LSID
resolution system.

If we used URN it would still not be clear what "kind" of URN.

Also remember that just because their is a defined field does not mean you
are obligated to use it.

We could also define a field *hasScientificNameURN* for non-resolvable URNs.

What I would like to avoid are cases where consuming agents including
crawlers generate an error when they try
to resolve an LSID by assuming that it will work like proper semantic web
URI's. In some cases, these system
stop processing when they encounter these errors.
