DTV — Inconsistent Use of ‘Concept Type’

Each kind of time point is a ‘concept type’. That is, the instances of each kind of time point are themselves concepts.

The specification is inconsistent about this. Referring to the beta 2 document:

Figure 10.2 shows the following as <<concept type>> but the text does not:
calendar day
calendar week
calendar month
calendar year
Figure 11.1 and the associated text do not mark these concepts as ‘concept type’, but should:
Gregorian day
Gregorian week
Gregorian month
Gregorian year
Figure 11.3 and the associated text do not mark these concepts as ‘concept type’, but should:
common year
leap year
centennial year
quadricentennial year
Gregorian day of year
Gregorian day of month
Gregorian month of year
Figure 11.7 shows the following concepts that should be marked <<concept type>>
Gregorian year
Gregorian day
Figure 12.1 and the associated text do not mark these concepts as ‘concept type’, but should:
calendar week
week of year
day of week
weekday of year
Figure 13.1 and the associated text do not mark these concepts as ‘concept type’, but should:
hour of day
minute of day
second of day
leap second
minute of hour
second of minute
Figure 13.3 shows the following concepts that should be marked <<concept type>>
hour of day
minute of day
Figure 14.1 shows the following class ‘internet time point’ that should be marked <<concept type>>, but that is missing from the text

Every specialization of ‘time point’ is marked ‘concept type’. The text and the figures are aligned wherever required.
