Paragraph annotations #2

We would like to have the ability, to annotate paragraphs (and possibly other blocks as well) with additional attributes like class and id.

We like to use a syntax with braces ({}) for the annotation and the querySelector syntax (. means class, # means id etc.) from javascript for the specific attributes (although we might introduces our own syntax for data- attributes or whatnot).

Example

	This input should yield an annotated paragraph {.annotated, #foo}

Should result in

	<p class="annotated" id="foo">
		This input should yield an annotated paragraph
	</p>

Tasks

write unit tests
extend lexer
extend parser
write example in readme
make shure, this does not break other blocks
make shure, only {} blocks at the end of paragraphs are respected
