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.

Subject: [DFDL-WG] escapeKind clarifications needed.
Sent by: dfdl-wg-bounces@ogf.org

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.
