If Doug (and Michael) are fine with this change, I'm fine
with it, too.

However, it isn't really explicit in the document, and should be. This is a minimal change to that end (although other wording would be possible).

>>Here is my reasoning. We can't guarantee complete stability over time. Whenever Deprecated or Preferred-Value are added, it changes the canonical form; or if the target of a Preferred-Value is itself deprecated. Currently if a subtag is deprecated in a source standard in favor of another, nothing special needs to be done unless:

>>In the first 2 cases, we are forced to use a "special" code, eg change MM to 104. That's perfectly fine in the case of collisions (#1). However, it is completely unnecessary in the case of older deprecated codes. So my proposal is to change the above lines to drop the first one, and change the second to:

Values in the 'Deprecated' and 'Preferred-Value' MUST NOT be changed unless the tag or subtag in the Preferred-Value field is itself deprecated, or if a deprecation is reversed in one of the source standards.
