- Literal directive tokens acted as a way for a user to provide markup bits to be required when parsing a directive.
- Removed source implementations.
- Removed tests validating the feature.
#969
- Based generic directive implementation off of descriptors.
- Added parsing logic to consume descriptors and parse content that's expected.
- Added parsing errors to automagically detect unexpected directive pieces.
- Updated visitor implementations to understand the directive bits.
- Added a builder abstraction to easily create descriptors. Had to maintain the ability to manually construct a descriptor to enable convenient serialization/deserialization.
- Added tests/comparers to verify correctness of parsing.
