Summary: XInclude random behaviour

Initial Comment:
There is a problem with the XInclude system in eXist. Sometimes xi:include elements are parsed and the target included, and sometimes not when they really should be.

Take the following two example documents in the exist database:

- /db/fui/sdt/as/ALC1_FULL.xml:

<?xml version="1.0" encoding="UTF-8"?>
<config xmlns:xi="http://www.w3.org/2001/XInclude">
    <xi:include href="/db/fui/sdt/systems.xml#xpointer(//system[@name='ALC1']/*)"/>
    <parameter name="version">1</parameter>
    <parameter name="inst_server">server1.example.com</parameter>
</config>


- /db/fui/sdt/systems.xml:

<?xml version="1.0" encoding="UTF-8"?>
<template>
    <system name="ALC1">
        <parameter name="bu">SDT</parameter>
        <parameter name="env">ALC1</parameter>
        <parameter name="db_sid">d1rwa</parameter>
    </system>
</template>


Now run the following XQuery:

<root>{doc('/db/fui/sdt/as/ALC1_FULL.xml')/config}</root>

The result is as expected:

<root>
    <config>
        <parameter name="bu">SDT</parameter>
        <parameter name="env">ALC1</parameter>
        <parameter name="db_sid">d1rwa</parameter>
        <parameter name="version">1</parameter>
        <parameter name="inst_server">server1.example.com</parameter>
    </config>
</root>

But now expand the query a little bit to be slightly more specific:

<root>{doc('/db/fui/sdt/as/ALC1_FULL.xml')/config/parameter}</root>

You'd expect this to return the same set of parameters except without the surrounding config element. But no, the result is:

<root>
    <parameter name="version">1</parameter>
    <parameter name="inst_server">server1.example.com</parameter>
</root>

The xi:include is suddenly not included anymore!

This happens on both eXist 1.1.1-newcore and eXist 1.0.2-rev5396
