Re: [Bug 184] Clarifications requested for section 19.8 on hosting malicious content

Servers "need to" consider additional precautions?  If this text is  
meant to be normative, it isn't -- no MUST and "consider" is  
naturally vague.  So I assume this text is only meant to be advisory,  
do we need to make that clear?

I suggest using the same kind of wording as  used elsewhere in the  
paragraph:  "Servers that allow clients to publish arbitrary content  
can usefully implement precautions to check that content is not  
harmful to other clients."
