one more note on this -- it uses "qnames in content" -- a difficulty
with this is that namespace prefix ("standard") are not significant
themselves, but only serve to connect a name with a URI.  So an
XSL transform could rewrite
<openraster xmlns:standard="http://www.example.org/or/1.0">
    <filter name="standard:blur"...

to
<openraster xmlns:ns1="http://www.example.org/or/1.0">
    <filter name="standard:blur"...

I.e. it would change element names, but would not know about
the "standard" in the name attribute.

In XSLT 2 it's possible to declare the name to be a qname, and then
the XSLT implementation will change it there too, to ns1:blur or
whatever.

Using <standard:blur> ... avoids this.
