Add templates to render change annex in module documents

[manuelfuenmayor]

As per https://github.com/metanorma/iso-10303-templates/issues/11

[manuelfuenmayor]

Issues to solve:

• :edition: document attribute is not accessible within yaml2text block via {edition}.
• Every module document must have a changes_paths.yaml, just like part 1051.

The variable “edition” conflicts with the document attribute also called “edition”? But in YAML is it possible to use something like “data.edition” to refer to it?

@ronaldtse, no. The issue is: we need access to the "edition" document attribute inside the yaml2text block (not a variable edition).

Outside yaml2text, :edition: value can be accessed by doing {edition}, but inside, I get empty string.

That is:

= Document attributes
:edition: 10

== Clause

{edition} // renders 10

[yaml2text,...,data]
----
{edition} // empty
----
