Ok. Perhaps we should add an optional attribute also, for specifying the 
used code standard, if any? That should not affect current implementations I 
think. Problem is that you cannot do anything with an abbreviation if you do 
not know what it means. Making assumptions can be dangerous. For instance 
you could asume that "SW" means Swedish, or that it means Swahili. If you 
know that it is an IANA subtag, you can use it and you can also raise an 
error if there is an abbreviation which is not present in the used standard.

Another comment about the Tapir metadata: when giving courses in installing 
Tapirlink, I noticed that none of the about 10 (Dutch) students could figure 
out themselves what 'relatedEntity' means. They all needed help on that. 
Perhaps the documentation of that element should be expanded?

Cheers,
Wouter
