I want to turn wikitext into HTML for display on a web front-end I'm building.  For what I'm doing, all I need is a few constructs like wiklinks, bold, and italic, which I'm able to do with a smallish amount of mwparserfromhell code. The one annoyance I've got now is I'm using bootstrap <https://getbootstrap.com/> in a web front-end, so I don't want <b> and <i> HTML tags.  I want is <span class="fw-bold"> <https://getbootstrap.com/docs/5.0/utilities/text/#font-weight-and-italics>  (and likewise class="fst-italic") Is there some way to tell mwparserfromhell.nodes.Tag to use that alternate markup when it processes bold or italic wikicode?

That only works on the content of an entire page, doesn't it?  I've just got a short snippet of wikitext that I've already parsed out of a page.

 Specifically, a proposed DYK hook, such as: > that '''[[Edward A. Hanna]]''' wanted to eliminate the [[New York > State Assembly]] while he served in it, and later wanted to close down > the government of the city of [[Utica, New York|Utica]] while he was > its mayor?
