Function specification description (FSD)

This is a new SCL type file containing only ONE Function element, hosted inside Template Substation, Template VoltageLevel and Template Bay like so:

<Subtation name="TAMPLATE">
  <VoltageLevel name="TEMPLATE">
    <Bay name="TEMPLATE">
      <Function name="...">
        ...
      </Function>
    </Bay>
  </VoltageLevel>
</Substation>
<DataTypeTemplates>
  ...
</DataTypeTemplates>

It is meant to be the smallest possible atomic particle that you can have during the template specification. Depending on the design of the rest of the engineering process, these files can be used to be imported into applications to create ASD files. They may as well be used to create System Specification files (SSD).
