3. Character entities
- Text entities (é, &companyName;) have to
be declared using DTD syntax (<!ENTITY ...>).
- They are invisible to schemas, tbe parser replaces them on the fly, liek a C Preprocessor macro
- You can't declare entities in SOAP payloads, only in the
outermost DOCTYPE subset or DTD
- Is five years too long to wait? DO we need XML 1.5?
