Phill, I agree with your bottom line here, removing "working group" and changing "no prior", although I am not sure that nominal is precisely right either - how about "the autor may have little or no knowledge of accessibility"? Charles McCN On Fri, 10 Dec 1999 pjenkins@us.ibm.com wrote: William and Gregory, I am confused why you make the comment "... I'll certainly go along but there is obfuscation caused by proliferation of endlessly growing volume of explanatory material designed ..." when I was proposing to "reduce" the text in the 2 Dec draft that was pointed to as a resolution of the issues raised during proposed rec. I understand your comment, I just think it should have been guided at earlier text proposed. Charles, I appreciate your constructive comment on the "... the idea that an author would be familiar with the language produced by the tool was implicitly rejected ..." and that "...that an author cannot be expected to know the nuts and bolts, only how to use a tool..." That is why I did not use the phrase "familiar with", but I used the phrase "aware of the language supported" to support the notion that a user chooses a tool because of it's capabilities which includes the "languages supported", or at least the notion that the tool supports publishing on the Web by converting RTF to HTML, or PDF, or whatever language formats the tool supports. I had thought that the assumptions going into selecting the priorities did assume that the author knew why she was using the tool and that is why I add the phrase to be explicit. I agree with Gregory when he says: "...whether or not an individual author has experience using a particular tool or a specific markup language does not materially affect the user's need to be guided, assisted, prompted, and encouraged to create accessible content ..." and I agree that needs are met when the checkpoints are implemented by the tool. In other words the selection of the checkpoints did not need to assume a particular level of user. But Gregory's statement does not explain the assumptions used to select the priority levels assigned to the checkpoints. I also agree with Gregory when he says: " ... the other goal of ATAG is to ensure that users with quote disabilities unquote will be able to use such tools to create accessible content ..." and that is why we have the goals stated in the document and Guideline 7. And again Gregory went on to say: "... how, then, can we expect them to be quote competent, but not necessarily an expert, user of the tool, unquote when use of such tools has been seriously curtailed, compromised, or stymied by the inaccessibility of the tool itself?" again, that is why we have priority 1 checkpoints in Guideline 7. However, I am now even more convinced that we need to document the assumptions about the level of the user [disabled or not] when we assigned the priorities. Our assumption is not "obvious" or we would not have had so many comments posted to the list. Gregory made the following assumption about the author's [tool user] skill level when he said: " ...it is _our_ priority to ensure that the broadest possible spectrum of authors (and _poetential_ authors) be given the opportunity to ..." and Gregory went on to say: "... what about the graduate of a web design course (or program of study) who hasn't learned a lick of markup, nor how to properly structure content and apply styles, but was only given a glorified introduction to a particular user interface? what constitutes being quote aware of the language supported unquote? ... that phrasing is so ambiguous that it could be taken to mean that the author is aware of the language supported because he or she chose to "Save as HTML"" and William said: "... it is as important to assume literacy and intelligence on the part of the developer, user, and casual reader of this document as it is to speculate about her knowledge of the interface, HTML, or accessibility concerns." But, since we agreed to document the assumed skill level of the tool user when Bruce raised the issue that the priorities could in fact change if we assumed a more motivated and knowledgeable user. Bruce said: "...[single] A used by highly motivated user, [double] AA average user who does not know about accessibility, [triple] AAA used by below average user." Because we are going to document our assumptions, I agree the verbiage should not assume too much, it should not ignore too much either, and it should not cause obfuscation by proliferation of an endlessly growing volume. I cannot support the removal of our assumptions from the document, but I can support what is in the 10 Dec draft with editorial changes: removal of the phrase "the working group has" and change "no prior" to "nominal": In choosing priority levels for checkpoints, the "author" is assumed to be a competent, but not necessarily expert, user of the authoring tool, and that the author has nominal knowledge of accessibility. For example, the author is not expected to have read all of the documentation but is expected to know how to turn to the documentation for assistance. Is there another proposal?
