Output of cat input.nmm:

[]	DEF

Observed output with bin/nmm nmm2xml input.nmm:

Perhaps we should expect the following output?

To expand on the above:

1. Paragraphs starting ⌜¶spaces*+TAG+line-break⌝ causes the paragraph to be tagged by TAG.
2. For items starting with ⌜TAG+line-break+TEXT⌝ causes the item to be rendered as ⌜TAG TEXT⌝, no tagging.
3. For items starting with ⌜TAG:name+line-break+TEXT⌝, the item is rendered as text ⌜SEMANTICS-OF(TAG)+TEXT⌝.

There is thus a discrepancy between how tags work for paragraphs and for items. This is not big issue, but should perhaps me solved. For that we first need to implement: #48
