TERMINOLOGY:

-- "slot" = A particular combination of case/number. Example slot names for nouns are "voc_s" (vocative singular) and "gen_p" (genitive plural). Each slot is filled with zero or more forms.

-- "form" = The declined German form representing the value of a given slot.

-- "lemma" = The dictionary form of a given German term. Generally the nominative masculine singular, but may occasionally be another form if the nominative masculine singular is missing. ]=]

--[=[ FIXME:

1. Qualifiers in genders should appear as footnotes on the articles. 2. Support notation like  on feminine/diminutive/masculine, e.g. used for Gespons (neuter with the meaning  "wife", masculine with the meaning "husband"). 3. Fix CSS gender-specific class in table. 4. Support adjectival nouns and adjective-noun combinations. (DONE) 5. Allow period and comma in forms e.g. for Eigent.-Whg., Eigt.-Whg. (using a backslash). (DONE) 6. Allow embedded links in genitive/plural/feminine/diminutive/masculine specs, e.g. 'f=!weiblicher Geschäftspartner'. 7. Add 'prop' indicator to indicate proper nouns and suppress the indefinite article. 8. Add 'surname' indicator to indicate surnames, decline appropriately and include both masc and fem variants in the table. (DONE) 9. Add 'langname' indicator to indicate langnames and decline appropriately with its own table with two alternatives. (DONE) ]=]

When we encounter a  multiword spec, we proceed left to right looking for a noun.

Finally, we set the property value for the multiword spec itself by combining all the non-nil properties of  the individual elements. If all non-nil properties have the same value, the result is that value, otherwise it is  `mixed_value` (which is "mixed" gender, but "both" for number). 3. When we encounter an alternant spec in this process, we recursively process each alternant (which is a multiword  spec) using the previous step, and combine any non-nil properties we encounter the same way as for multiword specs. 4.
