If you don「t pick up the correct SGML declaration when validating your XML, you will probably receive a lot of error messages.
如果在验证XML时,没有应用正确的SGML声明,则可能收到一些错误消息。
Because PSGML allows you to specify only one particular SGML declaration to be used, via the sgml-declaration (or sgml-xml-declaration for XML mode), the DTDDECL catalog feature can come in handy.
因为PSGML仅允许您指定一个要使用的特定sgml声明,通过sgml -declaration(或者xml方式的sgml -xml - declaration),就可以方便地使用DTDDECL目录特性了。
The SGML declaration establishes the basic rules for which characters are considered to be markup characters and which aren」t.
SGML声明确立了基础规则,以确定哪些字符是标记字符而哪些不是。
Again, assuming you installed SP in d: \ SP, an SGML declaration for XML will be in d: \ SP \ pubtext \ xml.dcl which is referenced by d: \ SP \ pubtext \ xml.soc (see the SGMLDECL entry).
我们再一次假设您在d: \SP中安装SP,则xml的SGML声明将在d: \SP \pubtext \xml .dcl中,该文件会被d: \SP \pubtext \xml .soc引用(请参阅sgmldecl项)。
