referencing a DTD

[Rod Davies <rdavies@orientpacific.com>]

As many would know, when Netscape reorganized their site 12 months back, 
they mistakenly deleted their RSS DTD, meaning many publishers with RSS 
feeds referencing this suddenly and without warning had problems. Netscape 
restored it very smartly after complaints, and stated that it was a mistake.

My question is, seeing Netscape does not have as much interest in RSS as 
previously is there another DTD we could use, which would be more 
permanent? Could anybody suggest some?

We are not programmers or developers, just publishers, which might be very 
evident! We use 0.91
