[Opendnssec-user] Weeks in Date Time durations

[Fred Zwarts (KVI)]

In the documentation of the Date Time durations I see:

Durations are represented by the format P[n]Y[n]M[n]DT[n]H[n]M[n]S. In these 
representations, the [n] is replaced by the value for each of the date and 
time elements that follow the [n]. Leading zeros are not required. The 
capital letters 'P', 'Y', 'M', 'W', 'D', 'T', 'H', 'M', and 'S' are 
designators for each of the date and time elements and are not replaced.

Note that in the format, there is no W, but in the explanation it says:

W is the week designator that follows the value for the number of weeks.

It looks to me that the documentation is not consistent.

I noticed that W is not accepted in kasp.xml. What is the rationale behind 
this? Or is it just a bug?
