/**
* Meta module that obtains values from other module and returns all
* parameters as XML.
*
* <p>Config</p>
* <pre>
* <!-- in cocoon.xconf -->
* <input-module name="request" ignore="do-" strip="user."/>
*
* <!-- e.g. in database.xml -->
* <mode type="all" name="xmlmeta" ignore="foo." use="foo" strip="f"
root="my-root"/>
* </pre>
*
* <p>If present, "ignore" gives a prefix of parameters to ignore,
* ignore has precedence over the "use" attribute, "strip" a prefix
* that will be removed from the final parameter names in the produced
* XML, "use" is a prefix for parameters to include in the XML, and
* "root" is the name of the root element in the created XML.</p>
*
* <p>Input</p>
* <pre>
* foo.one = ['abc']
* foo.two = ['def']
* foo1 = ['bar']
* foo2 = ['one','two','three']
* bar = ['rubber duck']
* </pre>
*
* <p>Output</p>
* <pre>
* <my-root>
* <item name="oo1">bar</item>
* <item name="oo2">
* <value>one</value>
* <value>two</value>
* <value>three</value>
* </item>
* </my-root>
* </pre>
*
* <p>Should produce Objects that are XMLizable and Document one
* day. Currently, produces only Strings.</p>
