--  <求助>一个关于DTD的问题
帮我看看我的DTD错误在哪里并修改它
外部DTD代码是:
<!ELEMENT account         (deposit,payment)+>
     <!ELEMENT deposit         (from,amount,date,description?)>
     <!ELEMENT payment         (to,amount,data,description?)>
     <!ELEMENT from            (#PCDATA)>
     <!ELEMENT to              (#PCDATA)>
     <!ELEMENT amount            (#PCDATA)>
     <!ELEMENT date            (#PCDATA)>
     <!ELEMENT description      (#PCDATA)>
      <!ATTLIST account
                    name CDATA #FIXED "Harold Roy"
                    number ID #FIXED "899-24390"
                    bank CDATA #FIXED "Central City Bank"  >
      <!ATTLIST deposit type (direct,cash,transfer,cheque) #REQUIRED>
      <!ATTLIST payment
                  payment (atm,cheque,transfer,withdrawal) #REQUIRED
                  chequeNum ID #IMPLIED
                   >
      <!ATTLIST from category income #REQUIRED>
      <!ATTLIST to category (utilities|entertainment|food|clothing|cash|other) #REQUIRED>
      <!ENTITY employer "Net World">

你对比的看看，应该和你原来的业务关系一样吧
我是用xmlspy编辑验证的。
另外，注意校验文档，里面有好些大小写字符了，或是两处写的不一样而造成的错误。
