In Part 7, the definition of data type Percentage is poor (see also Bug #463 https://bugzilla.datex2.eu/show_bug.cgi?id=463).

In CEN/TS 16157-2 the following contradictionary expressions can be found:

7.4.1.2 Semantics "A percentage as distance expression i.e. the ratio between the absolute distance [...]"

and

C.3.3.2 "Percentage [...] A value of 0 (zero) represents a location at the start of the linear element. A value of 100 represents a location at the end of the linear element."

Depending on the outcome of Bug #463, those two statements have to be adopted to the resulting definition of Percentage.
