can i specify fixed number of children in dtd?

For example <!ELEMENT book (pages)*>
I want the number of pages to be exactly or less than 100 instead of 0 or more.

Can i achieve the above?

Thanks in advance.

We can't specify fixed number of children in DTD...for that you can use XML Schema.in Schema,there are attributes 'minOccurs' and 'maxOccurs' attributes.

example :
if we have root element <mail> and we reguired child <to> minimum 1 time and maximum 100...we can try it by bellow code:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="mail">
<xs:complexType>
<xs:sequence>
<xs:element name="to" type="xs:string" minOccurs="1" maxOccurs="100"/>
<xs:element name="from" type="xs:string"/>
<xs:element name="subject" type="xs:string"/>
<xs:element name="body" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>

Thanks!
