Very nice! Just out of interest, would the following (or some slight
variation) be valid?
<:org.w3c
<:html.html>
<head>
<title>...</title>
</head>
<body>
<:svg.svg>
<rectangle>
....
Seems that the "." notation should be enough to identify that you're
specifying the name space (to some extent) and a colon ":" isn't
needed for this to work?
