Calling the XPath extension function serialize(x) if x is an empty nodeset.
In Firefox, it fails with a popup about a component failure.
For example:
<group ref="/path/to/parent">
<output value="serialize(x)" />
</group>
This will fail if x doesn't exist, or even if parent doesn't exist.
The only workaround I've found is a an instance with an empty element:
<instance id="empty"><data xmlns=""><empty /></data></instance>
<group ref="/path/to/parent">
<output value="serialize(instance('empty')/empty | x)" />
</group>
Here's a proposed change to the serialize function which makes serialize
return an empty string if there is no nodeset.
