However, it seems to me that Courtenay is wrong: an rsid doesn’t have to be completely randomly-assigned, so long as the seed is unique. A combination of MAC address and current universal time would, for practical purposes, provide a reasonable guarantee of uniqueness. <o:p></o:p></span></p><p class=MsoNormal><span style='mso-fareast-language:EN-US'><o:p> </o:p></span></p><p class=MsoNormal><span style='mso-fareast-language:EN-US'>Francis<o:p></o:p></span></p><p class=MsoNormal><span style='mso-fareast-language:EN-US'><o:p> </o:p></span></p><p class=MsoNormal><span style='mso-fareast-language:EN-US'><o:p> </o:p></span></p><p class=MsoNormal><span style='mso-fareast-language:EN-US'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0cm 0cm 0cm'><p class=MsoNormal><b><span lang=EN-US>From:</span></b><span lang=EN-US> Rex Jaeschke [mailto:rex@RexJaeschke.com] <br><b>Sent:</b> 26 June 2017 21:57<br><b>To:</b> SC 34 WG4 <e-SC34-WG4@ecma-international.org><br><b>Subject:</b> FW: Latest word on DR-16-0014<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span lang=EN-US>Feedback from the submitter.

I presume that the text you are proposing is the final version in the document, i.e. the edits to my new short version, not the edits to old longer version. If so, I have no objection to the rules. I am sorry my enquiry created so much work.<o:p></o:p></span></p></div><div><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p></div><div><p class=MsoNormal><span lang=EN-US>However, I must point out that if you do not specify random generation of Revision Save IDs in the second rule, some readers will presume that there is some way, or that they should devise some way, of checking all branched copies of a document, or a central database of their Revision Save IDs, before generating a new Revision Save ID. Since this is not practical, the only way to minimise the probability of a duplicated Revision Save ID is random generation from the values not already listed in the rsids element. Any other method will not minimise the probability of duplication. I make this point because, in my experience, even some of the best-educated people are easily confused by probability.<o:p></o:p></span></p></div><div><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p></div></div><div><p class=MsoNormal><span lang=EN-US><br clear=all><o:p></o:p></span></p><div><div><p><b><span lang=EN-US style='font-size:10.0pt'>Courtenay Inchbald</span></b><b><span lang=EN-US style='font-size:10.0pt;font-family:"Times New Roman",serif'> </span></b><span lang=EN-US style='font-size:10.0pt;color:blue'> </span><span lang=EN-US style='font-size:10.0pt;font-family:"Arial",sans-serif'>| T +44 20 8673 5640 | M +44 771 858 3535 | </span><span lang=EN-US style='font-size:10.0pt'>54 Elmfield Road London SW17 8AL </span><b><span lang=EN-US style='font-size:10.0pt;font-family:"Times New Roman",serif'>| </span></b><span lang=EN-US style='font-size:10.0pt;font-family:"Arial",sans-serif;color:blue'><a href="mailto:c@inchbald.com" target="_blank">c@inchbald.com</a></span><span lang=EN-US><o:p></o:p></span></p></div></div><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><div><p class=MsoNormal><span lang=EN-US>On 26 June 2017 at 08:01, Rex Jaeschke <<a href="mailto:rex@rexjaeschke.com" target="_blank">rex@rexjaeschke.com</a>> wrote:<o:p></o:p></span></p><blockquote style='border:none;border-left:solid #CCCCCC 1.0pt;padding:0cm 0cm 0cm 6.0pt;margin-left:4.8pt;margin-top:5.0pt;margin-right:0cm;margin-bottom:5.0pt'><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p></blockquote></div><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p></div></div></body></html>
