Dear all,

the information that a NetElement is valid (for operation) is currently
modelled with the attributes @validFrom and @validTo. A resulting small
example looks like this:

<netElement ... validFrom="2018-01-01" validTo="2018-12-31"/>

This implementation of validity times has two drawbacks:
* It is not possible to model other infrastructure states, e.g. "under
construction"
* It does not allow to model segmented validity times, e.g. before and
after a construction blocking

The second point is really essential. Therefore, I propose to change the
RTM modelling in the following way: instead of attributes @validFrom and
@validTo, use a repeatable child element <valid> with attributes @from
and @to to define the different segments of validity time. The resulting
small example may look like this:

<netElement ...>
<valid from="2018-01-01" to="2018-06-29"/>
<valid from="2018-07-02" to="2018-12-31"/>
</netElement>

Any feedback is highly appreciated...

Best regards
Christian
