[DFDL-WG] escapeKind clarifications needed.

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. -- Mike Beckerle | OGF DFDL Workgroup Co-Chair | Tresys Technology | www.tresys.com
