Writing inside a Lua filter

Writing inside a Lua filter

I am wondering what the best way to write a string in different formats as 
part of a Lua filter is.

For example, a block might have an attribute called 'label' which is a 
Markdown string, e.g., 'An *emphasised* idea'. I could use `pandoc.read` to 
turn that into a Document object. Can I turn the Document object into, 
e.g., a string which is HTML? I'm thinking of a 'write' function which 
corresponds to read.

The solution that occurred to me is to use `pandoc.pipe` and pass the 
string to Pandoc, like so: `pandoc.pipe("pandoc", {"--to", "html"}, label)` 
('label' is assigned a string). I get '<p>An <em>emphasised</em> idea</p>'. 
Is that a good approach?

That's probably the best you can do for now.
We don't export writers for Lua.
