I found this beautifully organized text for my students to analyze in terms of thematic progression. I'll also ask them to provide a transitivity analysis of some of its clauses, but there's that expression that caught me off guard.
I suppose it's a relational process 'be' followed by the carrier 'that' (which is already odd).
Then we get to 'as it may'. Would you say it's a conjunctive adjunct followed by a carrier and an elliptical attributive process (may be)?
Is there any other way to interpret it?
