Cannot add documentation to each field of a type using `@aml`

[singularitti]

The suggested way of adding documentation to each field of a type introduced in Julia's official documentation is no longer workable in @aml:

julia> @aml mutable struct Body "body"
           "field h1"
           h1, "~"
           "field p"
           p::Vector{String}, "~"
       end

Is this a new documentation feature?

It's been introduced since Julia 1.0.

I don't think I will add support for this. It is quite hard to parse it, and also it would be breaking since we are already using the docstring of the first field as the XML name of the struct.

Can this problem be solved if we move the XML tag before the struct's name, as I mentioned in #161 (comment)?
