TODO
In the source format of Markdown with with annotations...

the syntax for annotation *should be relatively human comprehensible
(in the same spirit as Markdown -- e.g. **strong emphasis**)
annotation syntax must not conflict with core Markdown
(i.e. must not cause disambiguations)
annotation syntaxt should not conflict with other Markdown extensions

For syntactically correct and structurally supported annotations...

visual output must be identical to source without the annotation
metadata of output must contain the annotation

For syntactically incorrect or structurally unsupported annotations...

the annotation must not disappear from visual output
visual output should include the annotation in source form
