Consider <option:text> syntax instead of <option<text>

[yc]

Most provide "matching bracket" functionality for <>, as with [], etc. This could be a hassle to work with if using the <option syntax

Were syntaxes like

Here is some <b:bold text>.
Here is some <i:italic text>.
Here is some <smallcaps:small cap text>.
Here is <bold, size +2:bold and larger text>

considered, with the first colon marking the separation?
