This is from the Expat Function Reference by Clark Cooper, which is a reference to the C api.   

"XML_Parser XML_ParserCreateNS(const XML_Char*encoding, XML_Char sep)
Constructs a new parser that has namespace processing in effect. Namespace expanded element names and attribute names are returned as a concatenation of the namespace URI, sep, and the local part of the name. This means that you should pick a character for sep that can't be part of a legal URI."

(from http://www.xml.com/pub/a/1999/09/expat/reference.html)

So thats what this function is for.  Now you know.

Internals has proposed[1] changing this extension from resource-based to object-based. When this change is made, xml_parser_create_ns will return an object, not a resource. Application developers are encouraged to replace any checks for explicit success, like:

<?php
$res = xml_parser_create_ns(/*...*/);
if (! is_resource($res)) {
    // ...
}
?>

With a check for explicit failure:
<?php
$res = xml_parser_create_ns(/*...*/);
if (false === $res) {
    // ...
}
