Synopsis
The <!DOCTYPE> instruction allows you to
specify a DTD for an XML document. This instruction currently takes
one of two forms:
<!DOCTYPEroot-elementSYSTEM "URI_of_DTD"> <!DOCTYPEroot-elementPUBLIC "name" "URI_of_DTD">
Keywords
-
SYSTEM The
SYSTEMvariant specifies the URI location of a DTD for private use in the document. For example:<!DOCTYPE Book SYSTEM "http://mycompany.com/dtd/mydoctype.dtd">
-
PUBLIC The
PUBLICvariant is used in situations in which a DTD has been publicized for widespread use. In these cases, the DTD is assigned a unique name, which the XML processor may use by itself to attempt to retrieve the DTD. If this fails, the URI is used:<!DOCTYPE Book PUBLIC "-//O'Reilly//DTD//EN" "http://www.oreilly.com/dtd/xmlbk.dtd">
Public DTDs follow a specific naming convention. See the XML specification for details on naming public DTDs.
