Marshalled XML не проверяет XSD, из которого был сгенерирован код

Question

XSD был доставлен моим клиентом, поэтому я не могу его изменить.Вот его начало:

<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema"
        xmlns:ocs="http://www.odette.org/OFTPCommunicationSetup"
        targetNamespace="http://www.odette.org/OFTPCommunicationSetup"
        elementFormDefault="qualified">
    <element name="OftpCommunicationSetup" type="ocs:OftpCommunicationSetupType"/>
    <complexType name="OftpCommunicationSetupType">
        <sequence>
            <element name="StationInformation" type="ocs:StationInfoType" minOccurs="1" maxOccurs="1"/>
            <element name="InboundCommunicationSettings" type="ocs:InboundCommunicationSettingsType" minOccurs="1"
                     maxOccurs="1"/>
            <element name="OutboundCommunicationSettings" type="ocs:OutboundCommunicationSettingsType" minOccurs="1"
                     maxOccurs="1"/>
            <element name="CipherSetting" type="ocs:CipherSettingType" minOccurs="0" maxOccurs="1"/>
            <element name="SessionSettings" type="ocs:SessionSettingsType" minOccurs="1" maxOccurs="1"/>
            <element name="OutboundFileSettings" type="ocs:FileSettingsType" minOccurs="1" maxOccurs="1">
            </element>
            <element name="InboundFileSettings" type="ocs:FileSettingsType" minOccurs="1" maxOccurs="1">
            </element>
            <element name="SubStations" type="ocs:SubStationsType" minOccurs="0" maxOccurs="1"/>
            <element name="Certificates" type="ocs:CertificatesType" minOccurs="0" maxOccurs="1"/>
        </sequence>
        <attribute name="version" type="string" use="required">
        </attribute>
        <attribute name="docid" type="ID" use="required">
        </attribute>
...

Генерируемый класс ´OFTPCommunicationSetup´ аннотируется так:

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "OftpCommunicationSetupType", propOrder = {
    "stationInformation",
    "inboundCommunicationSettings",
    "outboundCommunicationSettings",
    "cipherSetting",
    "sessionSettings",
    "outboundFileSettings",
    "inboundFileSettings",
    "subStations",
    "certificates"
})
public class OftpCommunicationSetupType {

    @XmlElement(name = "StationInformation", required = true)
    protected StationInfoType stationInformation;
    @XmlElement(name = "InboundCommunicationSettings", required = true)
    protected InboundCommunicationSettingsType inboundCommunicationSettings;
    @XmlElement(name = "OutboundCommunicationSettings", required = true)
    protected OutboundCommunicationSettingsType outboundCommunicationSettings;
    @XmlElement(name = "CipherSetting")
    protected CipherSettingType cipherSetting;
    @XmlElement(name = "SessionSettings", required = true)
    protected SessionSettingsType sessionSettings;
    @XmlElement(name = "OutboundFileSettings", required = true)
    protected FileSettingsType outboundFileSettings;
    @XmlElement(name = "InboundFileSettings", required = true)
    protected FileSettingsType inboundFileSettings;
    @XmlElement(name = "SubStations")
    protected SubStationsType subStations;
    @XmlElement(name = "Certificates")
    protected CertificatesType certificates;
    @XmlAttribute(name = "version", required = true)
    protected String version;
    @XmlAttribute(name = "docid", required = true)
    @XmlJavaTypeAdapter(CollapsedStringAdapter.class)
    @XmlID
    @XmlSchemaType(name = "ID")
    protected String docid;
    @XmlAttribute(name = "docdate", required = true)
    @XmlSchemaType(name = "dateTime")
    protected XMLGregorianCalendar docdate;
    @XmlAttribute(name = "validfrom", required = true)
    @XmlSchemaType(name = "dateTime")
    protected XMLGregorianCalendar validfrom;
...

Маршаллированный XML из экземпляра объекта начинается так:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<OftpCommunicationSetup xmlns="http://www.odette.org/OFTPCommunicationSetup" docid="4cc78e17561f4e0a8062462e72b9939d" docdate="2019-06-13T15:29:08.099+02:00">
    <StationInformation>
        <DUNS>987654321</DUNS>
        <Name>Wiley E. Coyote Corporation</Name>
        <CompanyInfo>
            <Name>Wiley E. Coyote Corporation</Name>
        </CompanyInfo>
        <OdetteIDCode>O017700000000COYOTE000001</OdetteIDCode>
    </StationInformation>
...

Проверка этого XML на XSD теперь утверждает:

The XML-file is not valid with the according XSD-Schema cvc-datatype-valid.1.2.1: '4cc78e17561f4e0a8062462e72b9939d' is not a valid value for 'NCName'.

Я, честно говоря, не понимаю, почему этот UUID для атрибута docid не должен быть действительным NCName.NCName в основном требует, чтобы в ID не было ":", верно?
