Yes, thank you.

We havn't mirrored the mmCIF files yet for the JenaLib so I don't have 
an overview which ones are currently actually used.
With respect to future enhancements of highlight/selection options I 
would rather tend to include more options than less.

The distinction must also be available for reading mmCIF data from local 
files or variables.
The JenaLib for example wouldn't be able to use 'load *XXXX*' for 
generating more than 300,000 precomputed structure images for the whole 
PDB entries.
