A Good Thing, but not quite enough....

Is this an error for "FPI", or is this YAA (Yet Another Acronym)?

So far so good. But unfortunately, an XML namespace-name has to be
an URI, and there is as yet no way to map FPIs into URIs, as a
consequence of there being no official URNs yet.
The natural way would be "urn:fpi:+%2F%2FIDN%20drmacro.com%2F%2FDOC"
etc. etc. but that isn't official, just obvious. 1/2 :-)
