The fdsnstationxml xschema shows that the "number" attribute on a
<ResponseStage> is a CounterType, which is an integer with <xs:minInclusive
value="0"/>. However, general usage, and the output from the web service
generally count stages starting at 1. Might be nice to have the schema
enforce this convention by having a separate counter type that starts at 1
for the cases where that makes sense. Especially since the seed usage of
stage zero meaning "overall gain" would be confusing if someone indexed
their ResponseStages starting at zero per the xschema.

thanks

    And just to make sure I understand, in fdsnstationxml, there should never
    be a <ResponseStage> with number="0", correct? In the old seisFile, I had
    code that would check for a stage zero for overall sensitivity, but I think
    that should no longer be needed.

      Hi

      Following up, I found this in the comments. Sorry, I should read more
      carefully, but I think this is a leftover comment from the old station xml
      as the same text appears in the old stationxml schema doc? Presumably you
      would not have deprecated features in a brand new schema? Can you clarify?

      In this schema, stage 0 gains are allowed but are considered deprecated.

      thanks
      Philip
