Notes

Unsupported markup

The following markup will not supported because its functionality is duplicate or inconsistent with others markup, or not secure,

• Header

  • Subtitle partitioning. Rationale: duplicate with 14.1.2 the "Main: sub" format

• Tables

  • Nested tables. Rationale: nested table is not a good way to present information. Never should it be.
  • Using different cell separator

• Include Directive

  • Select Portions of a Document to Include. Rationale: the parser would need to know the language to be included and parse the whole source code to check for comments and tags.
  • Include Content from a URI. Rationale: security and unreliable network connections.
  • Caching URI Content

Unordered list item with hyphen

The unordered list item with hyphen ('-') cause too much confusion and inconsistency.

Case one, given the following markup,

- Item 1
+
"A line
of quote"
-- Author

Is the "Author" the sub item in list or we are parsing author of quote paragraph?

Case two, the writer want to write em dash (— in HTML Unicode) but somehow the editor wrap it and start in new line.

As a reminder, the official documentation only recommend using hyphen for simple list item

You should reserve the hyphen for lists that only have a single level because the hyphen marker (-) doesn’t work for nested lists. -- https://docs.asciidoctor.org/asciidoc/latest/lists/unordered/#basic-unordered-list
