>___Note that a SystemLiteral can be >parsed without scanning for markup.___ >I wonder what the last sentence really wants to say. A system literal is the URI string in something like <!ENTITY foo SYSTEM "http://whatever/foo"> or <!DOCTYPE foo SYSTEM "foo.dtd"> The point is that those strings can't contain any markup. Obviously they can't contain elements, but in particular they can't contain entity references, so you can't for example do <!ENTITY % myurl "http://whatever/foo"> <!ENTITY foo SYSTEM "%myurl;"> And if you have something like <!ENTITY foo SYSTEM "my%20url"> the %20 will work perfectly well as a URI-escape for the space character, and won't cause a syntax error as it would in an internal entity value. Contrast the EntityValue and AttValue productions [9] and [10] in which some characters are interpreted as markup with the system literal production [11] in which no characters are special except the quotes. -- Richard
