+Part of speech. Pronouns, determiners, predeterminers and articles are roofed by nouns and adjectives, and distinguished by values of other features. The ''num'' value is intended for cardinal numbers (''numtype = card''). Other types of numerals are roofed by syntactically defined parts of speech (adjectives or adverbs) and distinguished by values of ''numtype''.

 ===== tense =====
+Note: In Interset 1.0, there were two separate features, ''tense'' and ''subtense'', the latter consisting of the values ''aor'', ''imp'', ''nar'' and ''pqp''. We used to avoid hierarchical feature values (e.g. ''aor''ist implies ''past''; but many languages will only know ''past'' and their drivers will not check for the ''aor'' value). Hierarchical ordering of feature values is now normal and there are algorithms to exploit the hierarchy when a feature has to be replaced by another value, thus these two features have been merged.
+Note that, unfortunately, imperfect tense is not always the same as past tense + imperfective aspect. For instance, in Bulgarian, there is lexical aspect, inherent in verb meaning, and grammatical aspect, which does not necessarily always match the lexical one. In main clauses, imperfective verbs can have imperfect tense and perfective verbs have perfect tense. However, both rules can be violated in embedded clauses. Aorist is aspect-neutral and can freely appear with both imperfective and perfective verbs.

-===== subtense =====
-Finer classification of tenses, may not be available in all languages. (And in many languages, these tenses are built using auxiliaries, rather than special morphemes.) Having these separated from the main past-present-future distinction allows that drivers need not check for aorist/imperfect, if they know just one past tense.

 Only information that cannot be stored in other features should be stored here.
 The apparently easiest approach — to store the complete original tag — will not work if the user needs to change feature values between decode() and encode().
+Note that the ''tagset'' feature may sometimes refer to a related but different driver. For instance, drivers ''cs::pmk'' and ''cs::pmkkr'' are related. The latter is a reduced version of the former and its implementation uses the code of the driver for ''cs::pmk''. Both drivers share their interpretation of the values of the ''other'' feature. They thus also use the same value of the ''tagset'' feature, namely ''cs::pmk''. Sharing this identifier helps one driver understand the ''other'' values set by the other driver. The derived driver has its own identifier, ''cs::pmkkr'', but this identifier is never mentioned in the feature structures. It would be more precise to say that the ''tagset'' feature identifies the language used in the feature structure, rather than the source tagset.
