Do you mean a map collection like: [ "the answer is" => 42 ]

<doc schema="file:///Foobar">
    <question>the answer is</question>
    <answer>42</answer>
</doc>

This assumes that the schema for <file:///Foobar> is:

<doc schema="file://waterken.com/doc/schema/Schema>
    <annotation schema="file://waterken.com/doc/schema/Comment"/>
    <unordered>true</unordered>
    <children>
        <key_schema>file://waterken.com/adt/string/String</key_schema>
        <value_schema>file://waterken.com/doc/schema/Branch</value_schema>

        <element>
            <key>question</key>
            <value>
                <annotation schema="file://waterken.com/doc/schema/Comment" />
                <implicit>file://waterken.com/adt/string/String</implicit>
                <arity schema="file://waterken.com/doc/schema/Once" />

                The question.
            </value>
        </element>
        <element>
            <key>answer</key>
            <value>
                <annotation schema="file://waterken.com/doc/schema/Comment" />
                <implicit>file://waterken.com/Integer</implicit>
                <arity schema="file://waterken.com/doc/schema/Once" />

                The answer.
            </value>
        </element>
    </children>

    A property of the universe.
