This is caused by the usage of the complexContent tag.

Example:

<xsd:complexType name="SequencedTextType">
        <xsd:complexContent>
            <xsd:extension base="TextType">
...

The complexContent has an attribute named "mixed". The meaning of mixed is:

    mixed : Optional. Specifies whether character data is allowed to appear between the child elements of this complexType element. Default is false.
    For more info about complexContent, please refer to http://www.w3schools.com/schema/el_complexcontent.asp.

So mixed="false"  means it does not allow character data. Then the error, "text not allowed in empty content" is expected.

To fix this error, you can replace the complexContent with simpleContent if the complexType to be defined has only attributes and character data and no child element. Or you can add attribute mixed="true" to the complexContent tag if the complexType has attributes and a character data and child element.
