Possibility to define a data type for element that are mixed

Here is a section of my xml

<xsd:element name="GROUP">

<xsd:complexType>

<xsd:sequence>

<xsd:element ref="GROUP_TAG" minOccurs="0"/>

<xsd:element ref="DESCRIPTION" minOccurs="0"/>

</xsd:sequence>

<xsd:attributeGroup ref="ENTITY_ATTRIBUTE"/>

</xsd:complexType>

</xsd:element>

I've tried to declare the GROUP node as mixed and give him a data type, but 
it didn't work. See the following lines of codes.

<xsd:element name="GROUP">

<xsd:complexType mixed="true">

<xsd:complexContent>

<xsd:extension base="stNotEmptyTo255Length">

<xsd:sequence>

<xsd:element ref="GROUP_TAG" minOccurs="0"/>

<xsd:element ref="DESCRIPTION" minOccurs="0"/>

</xsd:sequence>

<xsd:attributeGroup ref="ENTITY_ATTRIBUTE"/>

</xsd:extension>

</xsd:complexContent>

</xsd:complexType>

</xsd:element>



I would like to be able to define the GROUP node as a mixed element with a 
string datatype with a minlength=0 and a maxLength=255. This will be really 
helpfull.

I've worked around it with other elements that do not contain a sequence, 
but I would like to be able to do it with an element that does contain a 
sequence.

<xsd:element name="GENERAL_LEASE">

<xsd:complexType mixed="true">

<xsd:simpleContent>

<xsd:extension base="stNotEmptyTo255Length">

<xsd:attributeGroup ref="ENTITY_VALUE_ATTRIBUTE"/>

</xsd:extension>

</xsd:simpleContent>

</xsd:complexType>

</xsd:element>



<xsd:simpleType name="stNotEmptyTo255Length">

<xsd:annotation>

<xsd:documentation>String with minlength = 1 and maxLength = 
255</xsd:documentation>

</xsd:annotation>

<xsd:restriction base="xsd:string">

<xsd:minLength value="1"/>

<xsd:maxLength value="255"/>

</xsd:restriction>

</xsd:simpleType>
