Existence of instances without a root-scope id.

[Denis Weerasiri <dd...@gmail.com>]

Hi all,
In pmapi.xsd the following element says there can be instances with-out a
root-scope. Is this possible to exist instances without a root-scope id?

<complexType name="tInstanceInfo">
        <sequence>
            <element name="iid" type="xs:string">
                <annotation>
                    <documentation>The unique instance identifier.
</documentation>
                </annotation>
            </element>
            <element name="pid" type="xs:string">
                <annotation>
                    <documentation>Process id of the process to which this
instance
                        belongs.</documentation>
                </annotation>
            </element>
            <element name="process-name" type="QName"/>
            *<element name="root-scope" type="pmapi:tScopeRef"
minOccurs="0">*
                <annotation>
                    <documentation>Root scope id (might not exist).
</documentation>
                </annotation>
            </element>
