                               DisplayHintAttribute

is a display hint.

Display hint literals are comma-separated key=value sequences. Keys are up to the application and evaluated by htmltable, votable, etc.

The parsed values are simply dictionaries mapping strings to strings, i.e., value validation cannot be performed here (yet -- do we want this? A central repository of display hints would be kinda useful...)
