Enhancement to make "N" a synonym of "PA" in Paragraphs
Previous Release Behavior
N was not legal in attribute 1 of paragraphs.
The paragraph ID was not case insensitive in the MD.
Paragraph keywords were not case insensitive.
Current Release Behavior
N is now a synonym of PA.
The paragraph ID can be used in a case insensitive manner.
Most paragraph keywords are case insensitive, e.g. DISPLAY is the same as display or Display.
This behavior requries Config_EMULATE option case_insensitive_md = true, which is set by default for the D3 emulation.
