Or, assuming your getting this document from somewhere on-line, if it's
important enough to be validated why don't you do the on-line validation at
the same time you download. You could then keep the document and
While I'm not prepared to say there is no need for CRLs, the implementation
I am looking at would be one supporting on-line validation.
Just my $.02.
