I have written code for radio button in the schema as :
<xs:simpleType name="my_choices">
<xs:restriction base="xs:normalizedString">
<xs:enumeration value="first_choice"/>
<xs:enumeration value="second_choice"/>
<xs:enumeration value="third_choice"/>
…
</xs:restriction>
</xs:simpleType>
<xs:element name="my_group">
<xs:complexType>
<xs:sequence>
…
<xs:element name="my_radio">
<!– force radios by using appearance="full" –>
<xs:annotation><xs:appinfo>
<alf:appearance>full</alf:appearance>
</xs:appinfo></xs:annotation>
</xs:element>
…
</xs:sequence>
</xs:complexType>
</xs:element>
my doubt is how to access the enumeration value defined the complex type as first_choice in xsl style sheet?
