Questions about a missing attribute

[Unaimend]

I just tried to rewrite one of my Python tools in Rust. But I was not able to find the following SBML section in the output that was produced by let doc: SBMLDocument = SBMLReader::from_xml_string(&content);. I usually use cobrapy and am not very familiar with raw SBML files, so maybe I just overlooked it.
So, is this already implemented?

 <fbc:listOfObjectives fbc:activeObjective="obj">
      <fbc:objective fbc:id="obj" fbc:type="maximize">
        <fbc:listOfFluxObjectives>
          <fbc:fluxObjective fbc:reaction="R_BIOMASS_Ecoli_core_w_GAM" fbc:coefficient="1"/>
        </fbc:listOfFluxObjectives>
      </fbc:objective>
    </fbc:listOfObjectives>

No, the ListOfObjectives is not yet implemented, but I am happy to add this asap.

That would be quite helpful. Thank you very much for your time

This would require a slight change to the vcpkg import, so that not libsbml but libsbml[fbc] is pulled. But i think it is fine to add libsbml extensions as people have a need for them.
