Dear List,
I have been reviewing the use of the axis attribute as defined in Chapter 5, and
comparing it to the trajectory example in the Chapter 9 document at A9.4. The
Ch. 5 rules states that only a coordinate variable can have an axis attribute,
whereas the auxiliary variables cannot. However, in Ch. 9, the single
trajectory dimension is time, but the variable z contains the axis attribute. Is
this a change to the rule as stated in Ch. 5, or a typo? I briefly looked over
the other feature types in Ch. 9, and they all look to have the vertical
variable listed with the axis attribute, so maybe it is a typo.
Thanks,
Chris
