왜 XML Schema인가? (3) l 다음 XML 문서를 고려 § 각 요소의 데이터가 특정 타입임 <? xml version="1. 0"? > <!DOCTYPE policies SYSTEM "policies. dtd"> <policies> <policy-number="14235465"> <policy-type>contents</policy-type> <start-date>12 -12 -2005</start-date> <annual-premium>127. 85</annual-premium> <number-of-claims>1</number-of-claims> <paid-up>true</paid-up> </policy> </policies> 5
