As I posted before, there are three classes of fatal errors mentioned in the XML recommendation: violations of well-formedness constraints (when detectable); declaration of a encoding which the processor cannot process; invalid references to entities. I find also the following 20 kinds of non-fatal errors: violations of validity constraints; unescaped & or < in character data; unescaped > in "]]>" that is not the end of a CDATA section; -- within comment; DOCTYPE declaration that is not before the first element; DTD that contains text other than markup declarations; "standalone='no'" in a non-standalone document; xml:space declared as other than type "(default|preserve)" user-defined language id not beginning with "x-"; 2-letter language id not from ISO 639; text declaration provided by reference to a parsed entity; text declaration not at the beginning of an entity; UTF-16 encoded entity doesn't begin with BOM; parsed entity not encoded in UTF-8 or UTF-16 lacks encoding declaration; encoding declaration doesn't agree with actual encoding; built-in entities declared incorrectly; system identifier contains fragment identifier (optional error); non-deterministic content model; non-supported XML version (optional error); version number is "1.0" but document conforms to another version; This list was compiled by looking at occurrences of "error" and "must". Not all "must"s appear here: "must"s that constrain the processor rather than the document are omitted, as are definitional "must"s like "If an element is empty, it must be represented either by a start-tag immediately followed by an end-tag or by an empty-element tag", where "must" really means "is". -- John Cowan http://www.ccil.org/~cowan cowan@c...
