   Would you know about any standards in this area?  Maybe you could get us
   started with a set of system flags that we could use in the compiler.

An outline of how system-flags (I dubbed them type/object modifiers)
could be implemented can be found in frontend/doc/Modifiers in the ooc
distrib.  A section of such flags is identified by [...], the location
of the section determines what Oberon-2 object (ie, a type, a
variable, a procedure, etc) is modified by them.  It's the back-end's
task to to parse the stuff inside the brackets.  That means that every
back-end has full freedom in the choice of its supported flags.
