Hai,
I am preparing dtd.Can I restrict user to specify a predefined entry for element.
for example..
<male>true</male>
male is a element.
I want, user can only specify either true or false.I know i can do it with XMLschema.

Moving to the XML forum.

Go to http://www.w3schools.com/dtd/dtd_attributes.asp and look the section titled "Enumerated attribute values".

With XML Schema, it's very easy, just use the type boolean:
<xs:element name="male" type="xs:boolean"/>
With DTD, as said Lasse, you have to use enumerated attribute values:
<!ATTLIST Element male (true|false) "true">
XML Example:
<Element male="true"/>
<Element male="false"/>
<Element/>
Hope this helps,
Cyril.
