We discovered that the arabic contextual analyzation OTP assumes
that any sequence of [0-9.+-]+ is a single number and should be
typeset in TLT mode.

For figure numbers and version numbers etcetera this assumption
is wrong (they are multiple numbers concatenated together).

A trick (?) is to change the separator such that the number
parsing in the otp see separate numbers as well:

   \setupcaptions[separator={{.}}]
