Is there a known source or author or textbook for this set of
"document standards" or composition principles? Are these in any way
lifted from an original source(s)?

purpose, logic, context, content, organization, presentation, and language

That is an interesting question.  The set of expressions sure
generally used when talking about language skills for school level
benchmarks, most commonly for the 7th to 9th grades, but one Wisconsin
site used them for the fifth grade.  Does Wisconsin have a better
school system?

Ultimately, the question I am asking is: has this list been
plagiarized from somewhere??

Maybe someone will correct my comment or be able to justify
plagiarism, but I doubt it.  Plagiarism reguires demonstrable proof of
the copying of a text or use of the plot or concept.  The very common
use of all the terms in so many documents would make it extremely
unlikely that plagiarism could be proven at this time.
