I'm sure I should know - but what is PME ?

It is good policy to assume that, even what may be a standard acronym
to the author, is not known by the reader and should always be spelled
out once fully in a document.

Maybe in an academic manuscript or something, but this here is the land
of Usenet where we have the benefit of FAQs, which exist for the purpose
of not having to explain everything every time (amongst other reasons)
