Cedric said:The second point in his summary is from the viewpoint that subsequent published material, such as the PHB2 or the FAQ, can impact the intent or function of rules published originally in the core RAW material, even where ambiguity exists.
The second contention is NOT presented from the standpoint that one MUST accept those sources as valid. It merely establishes the ruling if one CHOOSES to accept those sources as valid.
The problem that glass is pointing out (glass- feel free to correct me if I'm wrong) is that the Primary Source rule dictates when other sources (such as the PHB2 or FAQ) can impact the function of the rules. Alternate sources cannot change something "even where ambiguity exists", but rather only where ambiguity exists. In order for the FAQ ruling to be valid you have to believe that rules in the PHB are vague. This requires a looser, more "Artoomisish" reading than some people allow. If you use a stricter reading, and rule that the core rules do not allow INA for monks, then the fact that the FAQ and PHB2 say you can is irelevant.
For reference:
PHB Errata said:Errata Rule: Primary Sources
When you find a disagreement between two D&D® rules sources, unless an official errata file says otherwise, the primary source is correct. One example of a
primary/secondary source is text taking precedence over a table entry. An individual spell description takes precedence when the short description in the beginning
of the spells chapter disagrees.
Another example of primary vs. secondary sources involves book and topic precedence. The Player's Handbook, for example, gives all the rules for playing the game, for playing PC races, and for using base class descriptions. If you find something on one of those
topics from the DUNGEON MASTER's Guide or the Monster Manual that disagrees with the Player's Handbook, you should assume the Player's Handbook is
the primary source. The DUNGEON MASTER's Guide is the primary source for topics such as magic item descriptions, special material construction rules, and so
on. The Monster Manual is the primary source for monster descriptions, templates, and supernatural, extraordinary, and spell-like abilities.
