extension and knowntype

[Guy Bottu]

	Dear Jose and Peter,

I agree with Jose that imposing an extension for the infile name and hence 
limiting the user in the choice of file names would restrict the 
flexibility. Actually, I myself can only think at one case were it would 
work fine : for a databank in BLAST format, since the format itself does 
impose the extensions. Using the knowntype attribute is certainly a 
solution. I will discuss this with Marc Colet.

	Regards,
	Guy Bottu,
