RelaxNG autocomplete not respecting choice tag

[AndrewJayStudio]

In example.rng I have the code:

<define name="key.element">
    <element name="key">
        <attribute name="name">
            <ref name="keyname.type"/>
        </attribute>
        <ref name="structured.content"/>
    </element>
</define>

<define name="structured.content">
        <choice>
            <group>
                <attribute name="type">
                    <value>dict</value>
                </attribute>
                <zeroOrMore>
                    <element name="key">
                        <attribute name="name">
                            <ref name="keyname.type"/>
                        </attribute>
                        <ref name="structured.content"/>
                    </element>
                </zeroOrMore>
            </group>
            <group>
                <attribute name="type">
                    <value>arr</value>
                </attribute>
                <zeroOrMore>
                    <element name="item">
                        <ref name="structured.content"/>
                    </element>
                </zeroOrMore>
            </group>
            <group>
                <attribute name="type">
                    <value>name</value>
                </attribute>
                <ref name="keyname.type"/>
            </group>
            <group>
                <attribute name="type">
                    <value>null</value>
                </attribute>
            </group>
            <group>
                <attribute name="type">
                    <value>bool</value>
                </attribute>
                <choice>
                    <value>true</value>
                    <value>false</value>
                </choice>
            </group>
            <group>
                <attribute name="type">
                    <value>int</value>
                </attribute>
                <data type="int"/>
            </group>
            <group>
                <attribute name="type">
                    <value>num</value>
                </attribute>
                <data type="decimal"/>
            </group>
            <group>
                <attribute name="type">
                    <value>str</value>
                </attribute>
                <data type="string"/>
            </group>
        </choice>
    </define>

Which when trying to autocomplete in XML document, produces the following result:

<key name="" type="dict" type="arr" type="name" type="null" type="bool" type="int" type="num" type="str"></key>

This is unexpected, as it shouldn't be combining all the mutually exclusive choice operands. The expected result should at the very least not auto fill the attributes of <key/> and instead leave them as auto suggestions upon typing. The best case scenario would have something similar to <key name="" type=""></key> with tab-able auto suggestions between the attribute values. The validation itself recognizes that the produced result is invalid, giving Attribute "type" was already specified for element "key".xml(AttributeNotUnique).
