raw attribute in Pandoc's native format?

raw attribute in Pandoc's native format?

Hello, I am a new user. I apologize in advance should my question have 
already been covered (I did try searching) -- or make no sense! :)

Is it possible to use a raw attribute (raw_attribute extension) to express 
Pandoc's native format fragments? If yes, how?

As an example, Pandoc's native format allows this:
[Header 1 ("",[],[]) [Str "foo",LineBreak,Str "bar"]]
(note there is a "LineBreak" inside "Header")
for reference, this converts (as intended) to HTML as <h1>foo<br />bar</h1>

As far as I understand, it is not possible to express "LineBreak" inside 
"Header" via (simple) markdown (I might be wrong!), so I thought about 
raw_attribute.

So far I tried using variations (with/without commas) of
# foo`LineBreak`{=native}bar
but it did not work.

Thanks in advance! :)

You can use raw HTML, or just a code span with some content which does not
otherwise occur in your code spans and replace that with a LineBreak
element with a filter.

``````markdown
## First line.`LB`Second line.
``````

``````lua
function Code (elem)
  if 'LB' == elem.text then
    return pandoc.LineBreak()
  end
  return nil
end
``````

HTH,

Thanks! filtering is a good idea and very likely the best approach in such 
cases.
Mine was a rather borderline example, sorry - it was the best I could think 
of (based on a known limitation of markdown), I was mostly interested in 
the "general" question.

BTW, I did some further testing, so just for reference (should someone 
google this in the future):
to the best of my understanding "native" raw attributes are not actually 
"inserted" in the native AST (in the way, say, that html raw attributes are 
inserted into html) but left embedded in it as RawInline/RawBlock in the 
same way any other raw attribute is, for example:

`````markdown
`foo`{=native}
`bar`{=html} 
`baz`{=foobar}
````` 

gets converted to
`````native
[Para [RawInline (Format "native") "foo",SoftBreak,RawInline (Format 
"html") "bar",SoftBreak,RawInline (Format "foobar") "baz"]]
`````
(i.e. the native writer behaves in the same way no matter what the Format 
value is -- including nonexistent Format "foobar")

I think this is a very reasonable limitation, but in any case the current 
behavior can still be quite handy, since (as suggested by BP) it should be 
easy to filter the resulting RawInline (Format "native") elements (or, for 
example, Format "myproject").
