| top | pdf |

The category SUB_CATEGORY provides data items to describe a subcategory and to associate a procedure with the subcategory (see Section 2.6.6.2.9[link]). A subcategory is a set of data items within a category that have a particular association. A typical example would be a triad of positional coordinates x, y, z that are collectively assigned to a `cartesian' subcategory.
