[DFDL-WG] escapeKind clarifications needed.

[Steve Hanson]

It should be ignored with a warning according to spec section 2.2 (with 
errata applied).

o Property is not applicable because of another DFDL property setting. 
Warning (optional). Example is binaryNumberRep when representation is 
text.

When escapeKind='escapeBlock' we only use the escapeEscapeCharacter if 
needed to escape the block end. We don't use the escapeCharacter at all.

So, is it an error if escapeKind='escapeBlock' and you define a value for 
escapeCharacter in the same dfdl:escapeScheme? 

Such property cannot be inherited by scope, so since escapeBlock kind 
doesn't use the escapeCharacter, this can only be either an error, or 
silently ignored, or ignored with a warning.

An error is the best choice from a language design perspective.
