Duth,

Deprecating a feature normally means (at least):
   1) new constructs may not have defined behavior in conjunction with
      the deprecated feature
   2) future versions of the LRM may not define the construct (i.e.
      strictly speaking it would become illegal) or may not require
      support for compliance to the standard.

In reality, tool implementors don't arbitrarily cease to support
features, even when deprecated, due to backwards compatibility
concerns.  That being said, as a user, one might think twice
about designing *new* systems using a deprecated feature as one's
risk of having future problems definitely goes up.

Gord.
