I prefer the second solution explicitly stating the boolean service
parameters with value "false". Missing service parameters can be
interpreted as being "unknown". As suggested by you we then need to add
this set of "interpretation rules" in the railML Wiki [1].
The central question to be solved: do we need to have a complementary
information with the attribute <ocp><propOperational>@trafficType in
addition to the attributes in <ocp><propService>? Any comments on this
question are highly appreciated.

This conflict could be solved by changing the current attribute
<ocp><propOperational>@trafficType into an element
<ocp><propOperational><traffic> that can be repeated. The modified
example may look like this:
<ocp id='ocp_DKT_B' name='Dresden-Klotzsche Bbf.' type='operationalName'>
<propOperational operationalType='station' orderChangeable='true'
ensuresTrainSequence='true'>
<traffic type="operational"/>
</propOperational>
<propService passenger='false' goodsLoading='false'/>
<designator register='RL100' entry='DKT B'/>
</ocp>
