Perhaps free-form annotation remarks could be memo/list of byte varying or whatever. But the fields I wish to do lookups on would be a pain in the gizmo if they were too big [for some systems]. I want to write a public spec, complete with domains and SQL scripts to populate the data. If we had 3000 character PGN tags, MS Access and many other popular database systems would fail. It would not bother my use any because I have a boatload of very nice database systems here [we are a database outfit]. But it would be a pest for others.
