[Exist-open] [IMPORTANT] Namespace handling in function calls changed in trunk
|

To conform to the standard, we have changed how namespaces are handled
when calling a function. Previously, if you called a function from
within an XML fragment, the function body used to see the same
in-scope namespace declarations as the calling code. This was clearly
violating the XQuery spec and has been corrected by Adam.
This means you now have to be careful when using default namespaces:
make sure the XML nodes returned from your function are still in the
correct namespace. For example, the following query:
declare function local:test() {
<h1>title</h1>
};
<html xmlns="http://www.w3.org/1999/xhtml">
<body>{local:test()}</body>
</html>
does now (correctly!) return
<html xmlns="http://www.w3.org/1999/xhtml">
<body>
<h1 xmlns="">title</h1>
</body>
</html>
The xhtml namespace is no longer "inherited" by the called function.
So if your queries stopped working after updating trunk, just check
all function return XML in a default namespace.
