Thanks for working on this, Matt! Comments below. The changes will appear

Okay, added.

Sorry, I'm not understanding this issue. Can you expand on this? Currently
we have:

<Precursor>
  <CvParam cvRef="MS" accession="MS:1000040" name="m/z" value="862.9467"/>
  <CvParam cvRef="MS" accession="MS:1000041" name="charge state"
value="2"/>
</Precursor>

What's wrong with this and what are you proposing?

Thanks,
Eric
