I'm thinking we may have gotten our wires crossed in that line. The title
is not instead of the class but in addition to. So a <transChange
type="tenseChange"> is replaced with <span class="transchange" title="Verb
tense changed"><span class="tenseChange">**textual content of
original**</span></span>

So the CSS still works as intended. Granted, you can set CSS selectors on
arbitrary attributes with XPath-inspired syntax if you have a new enough
rendering engine, which both BibleTime and Xiphos have at this time. Based
on the code, I'm guessing this handling was originally limited to only
added and tenseChange and later people just got a little lazy with it and
didn't add in those titles.

It's translated the same way every other UI string in BibleTime is
translated.

                    buf.append("<span class=\"transchange\" title=\"");
                    buf.append(QObject::tr("Verb tense
changed").toUtf8().constData());
                    buf.append("\"><span class=\"tenseChange\">");

At least in the QtWebKit bindings, you can listen in on mouseover/hover
events and pull out the text of the elements to display it however you want.

Also, to be clear, I wasn't suggesting that this BT code is /the way to
go/, I was just answering Troy's question about how do those frontends
which customize their HTML renderers handle the transChange element by
telling him what the BT code does for the sake of comparison and discussion.
