It is true that the line Takuki Kamiya found is in error. That much is clear.

But if anything else is clear, it's that this issue that David claims is clear isn't clear. I was the one who argued this before, and I don't want to reopen the discussion, but I continue to read the following text (quoted from 4.6 aka http://www.w3.org/TR/REC-xml#sec-predefined-ent): If the [predefined] entities in question are declared, they must be declared as internal entities whose replacement text is the single character being escaped or a character reference to that character, as shown below. [which is then followed by a list of declarations for the 5 predefined entities] to say that it is not permissible to declare those 5 entity references any differently than as shown in that table. Perhaps it is possible to read the "as" in "as shown below" to mean "in a vaguely similar manner that does not change the standard effect", but that is a somewhat non-standard meaning in my experience. Nowhere in 4.6 does the word "redeclare" appear (as in "may redeclare"). In fact, after a couple uses of "may" in the first paragraph unrelated to the predefined entities themselves, the word "may" does not appear in section 4.6. It is at least reasonable to believe (as I do) that the "must be declared" in section 4.6 which I include in my quote above modifies, among other words, the "as shown below" phrase implying that it is an error to have a declaration for any of these 5 entities that differs from that shown in the table. paul xml-dev: A list for W3C XML Developers.
