Oh, arsebiscuits, sorry about LJ's HTML-eating, there; there really really needs to be a "verbatim" setting where nothing gets auto-interpretedbollocksed. (I suppose the standard OSS answer applies: if I want it, I should write it rather than whinging.) Did what I said make any sense in the email notification?

Coming back to yer blocks/inlines, I am pretty sure (after some hasty revision of what SGML knowledge I used to have) that %block;|%inline means one-or-more block XOR one-or-more inline.
