out of interest what does print_r() actually output? better yet what does
var_dump() actually output? (i.e. post the output please)

that'll be designating namespaces.
although I never knew you could stipulate as namespace in
a tag that actually references/loads said namespace:

<domain:chkData xmlns:domain="urn:ietf:params:xml:ns:domain-1.0"
xsi:schemaLocation="urn:ietf:params:xml:ns:domain-1.0 domain-1.0.xsd">

BTW: I remember reading about problems with namespace when using simpleXML (actually I remember
reading that namespaces where not supported) - this information maybe completely wrong (or
just out of date), anyway check the php-internals archives for more info on that

I'm all out of gas, oh hang on I don't even like XML that much :-) - with php4
I found XML a bit nightmarish, and all that namespace stuff can, well, really
screw up your day... I think Uroš knows that already :-/
