Hi Nicholas,

I was just surfing through web and came across a web site.
http://www.backbase.com/demos/pim/
It showed me some ajax examples. When i saw source of pages,
It looked kind of tricky to me. It used two namespaces called 'b' and 's'.
And each of them were used for some custom tags.
So i validated the page but got lots of error messages (XHTML Strict 1.0).
I just want to know if these custom tags are fine to use?
They look cool to me and might be useful in differentiating,
while building a good AJAX application.
But i don't want to go off the standards.
What do you think?

Technically, you should be able to include other namespaces in your XHTML code and have it still be valid. The W3C validator assumes that you have only XHTML code contained in the page, and so anything else will result in a bunch of errors messages.

Hi Nicholas,

Thanks for reply.
I expected a longer reply. But it's ok.
Hey, I m new with namespaces in XHTML.
I have worked with them in XML.
But I don't know how to use them in XHTML.
You might be busy and i can understand that.
Can you do me a little favor though,
Can you suggest any article,link or a book on using namespaces with XHTML.
I m getting freaked out by this topic,
and I want to use it in my further Ajax applications.
That will be very helpful for me.
