Code generator can add multiple text nodes

[tefra]

And here's the xsd that disproves the rule of one text node per model and is blocking the #246

  <xs:element name="appendix" substitutionGroup="chap">
    <!-- valid restriction of the base type -->
    <xs:alternative test="@type='date'">
        <xs:complexType>
            <xs:simpleContent>
                <xs:extension base="xs:date">
                    <xs:attribute name="type" type="xs:NCName"/>
                </xs:extension>
            </xs:simpleContent>
        </xs:complexType>
    </xs:alternative>
    <xs:alternative test="@type='dateTime'">
        <xs:complexType>
            <xs:simpleContent>
                <xs:extension base="xs:dateTimeStamp">
                    <xs:attribute name="type" type="xs:NCName"/>
                </xs:extension>
            </xs:simpleContent>
        </xs:complexType>
    </xs:alternative>
    <xs:alternative test="@type='time'">
        <xs:complexType>
            <xs:simpleContent>
                <xs:extension base="xs:time">
                    <xs:attribute name="type" type="xs:NCName"/>
                </xs:extension>
            </xs:simpleContent>
        </xs:complexType>
    </xs:alternative>    
  </xs:element>  

@dataclass
class Appendix:
    """
    :ivar value:
    :ivar value_1:

    class Meta:

That's actually my only sample 😳 out of all the w3c tests and samples
