If "fasta" format is defined as the format of a library that "fasta" 
(and perhaps blast) can read, then
I do not believe there is a requirement for any text after the '>'.

Thus,

	>
	acgtacgtacgt

Would be acceptable.  Of course, if you had a large library of:

	>
	acgtacgtacgt
	>
	tgcatgcatgca
	>
	gcatgcatgcac

It might be very difficult to distinguish the sequences.

I have seen many people use the perfectly acceptable

	>    [blanks] description 1
	asdf
	>    description2
	qwerty
