Feature Request: Allow multi-line text with fields as a Record.

I notice that Annotations and Records both have the type Record - which tells me there is room in the data model for a block of text and some fields.

What I want to do is to have a multi-line block of text and combine it together with some fields. This is for a situation where I will be showing some source code and highlighting a position within the code, and it would be nice if I could give the example source code over multiple lines.

I tried to get the parser to work with mulitple lines by guessing how they might be represented:

[some source text
over multiple lines]{source| pos = (0,0)-(1,10)}

|> Source
some source text
over multiple lines
    pos = (0,0)-(1,10)

|> Source
    source = some source text
over multiple lines
    pos = (0,0)-(1,10)

None of which work. The only way to combine text with fields as a Record, seems to be the single line annotation form:

[text on single line]{ann| ... fields }

Is there some way to combine multi-line text with some fields to form a Record? If not, it would be a nice feature to have, and I think the data model already has room for it, so only needs a new format added to the parser.

Format 2 above would be the nicest to work with.

I also tried putting a block within a block to see if it could be done that way:

|> Source
    Line 1
    Line 2
    |> Highlights
        -- (0,0)-(0,1)
        -- (1,3)-(1,5)

But this does not seem to work, and the inner block is just taken as text.
