Section 16.2.2 says:

<xs:attribute name="amt" use="optional">
    <xs:simpleType>
        <xs:restriction base="xs:integer">
            <xs:minInclusive value="-96"/>
            <xs:maxInclusive value="96"/>
        </xs:restriction>
    </xs:simpleType>
</xs:attribute>

It should say:

<xs:attribute name="amt" use="optional">
    <xs:simpleType>
        <xs:union>
            <xs:simpleType>
                <xs:restriction base="xs:integer">
                    <xs:minInclusive value="-96" />
                    <xs:maxInclusive value="96" />
                </xs:restriction>
            </xs:simpleType>
            <xs:simpleType>
                <xs:restriction base="xs:string">
                    <xs:enumeration value="mute" />
                </xs:restriction>
            </xs:simpleType>
        </xs:union>
    </xs:simpleType>
</xs:attribute>

Notes:

Section "8.12.1.1 <gain>" says, for the "amt" attribute of the <gain> element:

"amt: a specific gain to apply specified in dB or the string "mute"
indicating that the stream should be muted. This attribute MUST
NOT be used if "agc" is present."

However, in section "16.2.2. msml-conf-core-datatypes.xsd" the provided schema does not allow the value "mute", only integers. Either the XSD should be corrected as suggested, or the part
'or the string "mute" indicating that the stream should be muted' removed from the description.
