To use the external DTD we have the syntax
A. <?xml version=”A.0” standalone=”no”?>
<! DOCTYPE DOCUMENT SYSTEM “order.dtd”?>
B. <?xml version=”A.0” standalone=”yes”?>
<! DOCTYPE DOCUMENT SYSTEM “order.dtd”?>
(3 )<?xml version=”A.0” standalone=”no”?>
<! DOCTYPE DOCUMENT “order.dtd”?>
D. <?xml version=”A.0” standalone=”yes”?>
<! DOCTYPE DOCUMENT SYSTEM “order.dtd”?>
