xml-dev - A nice propeller head XML question :-)

[Dean Roddey <roddey@us.ibm.com>]

If the expansion of an entity reference is required to have a space on either
side of the expanded text, correct? If so, then something like this must be
invalid?

<!ENTITY % Foo 'ENTITY'>
<!%Foo; Bar 'Baz'>

right? Because the expansion of Foo requires that spaces be placed on either
side, creating this:

<! ENTITY Bar 'Baz'>

and the production for a PE declaration is:

PEDecl ::=  '<!ENTITY' S '%' S Name S PEDef S? '>'

which does not allow any space between the ! and ENTITY.

Is this correct? Basically what I'm looking for here is a more general rule
which says that I can consider any %blah; occurance at some place in the
grammar that does not allow spaces at that point to be in error without even
checking any further?
