The optional minclass= keyword specifies the minimum classification with which the word should appear in a human-readable label. The classification specified starts with the first non-blank character following the blank after the keyword, and continues up to the next semicolon or the end of the line. The classification can be either the short, long, or alternate name of a classification defined in the CLASSIFICATIONS: section. If the minimum classification with which a word can appear is the classification with the lowest value (as defined by the value= keyword), then there is no need to make a minclass= keyword specification.
If a word with an associated minclass is added to a label with a classification below that minclass, the classification in the label is automatically raised to the minclass, assuming the well formedness rules otherwise allow adding the word to the label.
