Hi Folks,

By definition these two forms are equivalent:

	<A></A>
	<A/>

Suppose a parser processes the first form and produces, among other things, a series of pairs (token kind, token value). Upon encountering this:

	<A>

the parser produces:

	(START_TAG_NAME, "A")

Upon encountering this:

	</A>

the parser produces:

	(END_TAG_NAME, "A")

Should this:

	<A/>

result in the parser producing the same two pairs?

What does "equivalent" mean? 

Assertion: "equivalent" means both forms result in the parser producing the same two pairs:

	(START_TAG_NAME, "A")
	(END_TAG_NAME, "A")

Do you agree?

/Roger
