Support for <details> and <summary>
Over at ruby/ruby, we sometimes have a situation in documentation where certain details may or may not be important to a few readers, but will be irrelevant to many.
E.g., @peterzhu2118 and I are looking at "Hash Equality and Inclusion", whose details may be important to a few but will be irrelevant to many. One of us thinks that info should be at a link; the other thinks it should be included inline.
There may be many other such.
Casting that info as <details><summmary>...</summary>...</details> would be a perfect solution. See <summary>.
Failing that, a weaker alternative would be support for <small>; see <small>.
In either case, support for embedded bold would be important (to give structure without adding headings), along with italic and monofont.
(I edited the links to descriptions of summary and small elements so that they render clearer here.)
