DTV11 — DTV Issue: Necessity for "time table" in clause 17.2

There are two problems with the Necessity in the entry for "time table" in clause 17.2:

1) The Necessity assumes a verb concept "time table has table entry" that does not exist.
2) The Necessity is misspelled as "Each time table must have at least one table entry." It should be "Each time table has at least one table entry. "

Note: the definition of "time table has table entry" should make clear the relationship of this concept to the "table entries" mentioned in the definition of "time table" as a "set of table entries".

The UML diagram (Figure 17.1) disagrees with the definition of time table, and introduces the missing verb concept (time table has table entry) as a specialization of ‘set has element’ (from SBVR). The UML model reflects the intent. The text will be revised to support the model.
