<memo>
The <memo> tag is a root-level document type for a memorandum. Like
<letter> or <article>, it starts a
document, but it is tailored to internal correspondence with memo-style
front matter such as to, from, subject, and date.
A memo can still contain ordinary PreTeXt body content, including
paragraphs and divisions like <paragraphs>.
