syntax_colour(?Class, ?Attributes) is nondet

True when a range classified Class must be coloured using Attributes. Attributes is a list of:

colour(ColourName)
background(ColourName)
bold(Boolean)
underline(Boolean)

Attributes may be the empty list. This is used for cases where -for example- a menu is associated with the fragment. If syntax_colour/2 fails, no fragment is created for the region.
