Auto-inserting correct xmlns attribute for html in XHTML

I always have to manually type the xmlns="http://www.w3.org/1999/xhtml"
attribute for the html element for XHTML 1.0 and 1.1 documents. psgml
doesn't seem to know about this attribute (i.e. it isn't available from
the Insert Attribute menu). This is a bit of a pain because I always
forget its proper value and have to look it up or copy and paste it from
another document. Is there some easy way I can get this attribute added
automatically when I insert the html element in XHTML documents?

TIA, Darren
