Headless Server delivers a ready to use implementation to parse and transform the CoreMedia rich text grammar 1.0, using the same techniques as described above. The implementation classes are

Though the CMGrammarRichTextAdapterFactory defines the grammar, which can be parsed by its corresponding RichTextAdapter, CMGrammarRichTextAdapter is grammar agnostic. CMGrammarRichTextAdapter implements a stax based parsing technology and can be configured using YAML files (see Section 5.1, “Rich Text Output” for details).

It is possible to reuse CMGrammarRichTextAdapter in a custom factory responsible for a custom grammar. This is an alternative of the first development step. If you consider reusing CMGrammarRichTextAdapter, keep in mind, that a grammar specific YAML configuration is necessary on top.
