The text you are referencing (the couple italic paragraphs below section
2.8 in the unprivileged ISA) is non-normative and "can be skipped if the
reader is only interested in the specification itself". This convention of
making indented italic text non-normative is described at the bottom of
page 1 of the linked document.
