DFC,
If by "ML" you mean microlight then the above is incorrect.
A JAR-FCL CRI can only provide training in SEP to a person who holds a JAR-FCL licence.
You're wrong with the above, since the SEP rating includes privileges relating to microlights.
I have written confirmation from the CAA that a CRI can provide training on microlight aircraft within the privileges of their class rating, since SEP includes microlights. See also LASORS section F.
In summary a CRI can complete SSEA to Microlight, or Microlight to SSEA or indeed Microlight to SEP, since it is CLASS RATING instruction.
ATB,
