Hmm ... this isn't very precise (says the guy who originally wrote it).  I think "the html" was shorthand for "in the `.html` file" ... it's really in javascript, that we do the monitoring, not the HTML.  We probably need a better name for this.  Maybe *view* file?  I'd be fine with leaving it as "the html" for now, if that doesn't make your skin wrankle.  We can revamp this when we do our greater overhaul of how the documentation flows.
