XSD notation question

Hi

I received following XSD schema from a client containing following
simpleTpe name and I am going to use it.
My question, is it allowed to use
point notation in XSD Schema for name declaration (bellow between 'InternalID'
and 'Content')??


<xsd:simpleType name="InternalID.Content">
               
<xsd:restriction base="xsd:token">
                    <xsd:minLength
value="1"/>
                    <xsd:maxLength value="32"/>
               
</xsd:restriction>
            </xsd:simpleType>
Thanks for your hint
