[vodml] EnumLiterals and vodml-id

[CresitelloDittmar, Mark]

All,

How about 'label'?  Though I have no strong opinion one way or the other.

I think the idea would be to present a 'real-world' equivalent to the token
which would be used for user interaction (eg: display).

In the DatasetMetadata instances
  SpectralBandType
    + "X-ray"
    + "Gamma-ray"

can move to
  SpectralBandType
    + name="xray"  [title|label]="X-ray"
    + name="gammaray"  [title|label]="Gamma-ray"

so the name can conform to a pattern, but still define a familiar
translation.
A similar thing could be done with the CreationType tokens.

>>Mark, Arnold, any problems simply making the 'name' of the enumliterals
conform to these rules?

I do think having the free-form option is important.  The values of these
enums are rooted in
the various standards (ObsCore, ResourceMetadata, VODataService).  I think
there is some
flexibility for making viable tokens, but would like to keep the full spec.
