I read the draft.

I liked the rationale/motivation in the Introduction.

I kept getting thrown by the asymmetry between “OS2IP” and “I2OSP” – shouldn’t that latter be “IP2OS” ? (Yes know 8017/PKCS1.5 is at fault)

Maybe use the half-open “[m,n)” notation as well?

The rest of the doc is just swell.  I like the comparison to other schemes. I thought “no duh” when reading the post-quantum section and wonder if it’s worth removing or reducing to one sentence.
