Syntax for meta-data

Shortcuts

One sure thing is that in attributes list #myid is a shortcut for id: myid and .myclass is a shortcut for class: myclass.

Meta-data for headers

For headers, you want to put metadata in the {} on the same line:

### Header ###     {#myid}

Header     {#myid .myclass}
------

Meta-data for block-level elements

For paragraphs and other block-level elements, you want to put the {} on the line below:

This is a paragraph.
Line 2 of the paragraph.

{#myid .myclass}

A quote with a citation url:
> Who said that?
{cite=google.com}

Meta-data for span-level elements

Moreover, you want to use a similar syntax for span-level elements. For example, in this:

This is a paragraph. *chunky*{#id1}
{#id2}

you are setting the id attribute to the em element to id1 and the id of the paragraph to id2.

This works also for links, like this:

This is [a link][ref]{#myid rel=abc rev=abc}

For images, it should be that

This is ![Alt text](url "fresh carrots")

is equivalent to

This is ![Alt text](url){title="fresh carrots"}

Using references

Then, it is possible to use references: {<number>} is threated as a reference (it is not ambiguous as attribute names cannot start with digits) and one can write:

### My header ### {1}
This is a paragraph with 
para para para
{2}

{1}: #header-id
{2}: #paragraph-id

which is equivalent to:

### My header ### {#header-id}
This is a paragraph with 
para para para
{#paragraph-id}
