Secure Parameters

Any idea how I could call the referenced fixlet through the API? We would be using the SourceFixletAction so something like this

https://bigfix.me/fixlet/details/3678

<?xml version="1.0" encoding="UTF-8"?>
<BES xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="BES.xsd">
 <SourcedFixletAction>
   <SourceFixlet>
     <Sitename>TestSite</Sitename>
     <FixletID>83</FixletID>
     <Action>Action1</Action
   </SourceFixlet>
   <Target>
     <ComputerID>13863357</ComputerID>
   </Target>
  <Parameter Name="_BESClient_EMsg_Detail">1000</Parameter>
 </SourcedFixletAction>
</BES>

It looks like the there is a SecureParameter element in BES.XSD so it looks like we might be able to do something like this?

<?xml version="1.0" encoding="UTF-8"?>
<BES xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="BES.xsd">
 <SourcedFixletAction>
   <SourceFixlet>
     <Sitename>TestSite</Sitename>
     <FixletID>83</FixletID>
     <Action>Action1</Action
   </SourceFixlet>
   <Target>
     <ComputerID>13863357</ComputerID>
   </Target>
  <SecureParameter Name="secret">SecureValueOfSecret</Parameter>
 <SecureParameter Name="secret2">SecureValueOfSecret2</Parameter>
 </SourcedFixletAction>
</BES>
