XSL default namespace!?

[blade134]

The default namespace used in XSL is:

xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

Even if a single character is changed in the namespace (inside quoted tags), I get parsing error.

The file is parsed successfully only if i gave the default namespace and parsing fails when I give any other URL.

1)So, I take it that its a pre-defined namespace..is that correct?

2)Also I wanted to know, whenever this default namespace is parsed,does the browser/parser logically checks for something in that web address?

1) I wouldn't call it pre-defined. It's just that what you think of as "xsl:stylesheet" is really "http://www.w3.org/1999/XSL/Transform:stylesheet". If you change even one character then you have changed the element name. You can, however, do this

<foo:stylesheet xmlns:foo="http://www.w3.org/1999/XSL/Transform">

2) Namespaces aren't checked and there is no requirement that they actually point to anything. They are only used as a unique identifier.

Thanks for the reply

I can see that it can be pre-defined and you need a unique identifier.
