Orbeon Namespace Lookup

Hi (still need a clever moniker for) Orbeon Users,

We think we have some delays happening because the xml parser
is looking up the namespaces such as:

http://orbeon.org/oxf/xml/formatting

We have already moved dtd files to a local copy, changing our
headers appropriately, e.g.:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "/
xhtml1-transitional.dtd">

And this improved things greatly -- we were really hit when the W3C
servers would slow.

A student reported this, so I have not tested this myself,
but I notice that, for example, entering the example at the top into
your browser
address bar and after the page is redirected to www.orbeon.com it
eventually times out --
not even an error.

I believe it is "customary" to have a page at the target of a URI used n
a namespace, not that it is required.

Thanks,
Hank

Clearly, the parser does not use a namespace uri besides for
strict comparison as a string. (As my student suggested.)

It does however for DTD uris...

But this made me realize something I had not noticed in
years, that many of the namespaces are "orbeon.org" :

http://www.orbeon.com/orbeon/doc/reference-xml-namespaces

and it is ... customary ... to have a landing page for
namespace uri's when they are urls, so perhaps that is
something to consider some point in the future.

Otherwise, I solved the slowness problem due to a broken
proxy serving little used resources.

Cheers,
Hank

True.

So are you saying that there is still a lookup for those resources
(i.e. DTD) done over the network? We wouldn't that to happen, and as
far as I know it doesn't (i.e. you should be able to access your form
deployed locally without an Internet connection).
