Won't do it, I'm afraid, 'cos I actually need to keep that crud, if it exists. Especially if somebody throws me the attributes in a different order:

<e st="obs" num="1" st="ali">
needs to group in the same way. By using ?: the entire intermediate string disappears, and I end up with
<e st="obs,ali">
Which wasn't precisely what I was after. Although it does shut the warning up :-)
