<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Regarding proposed handing of X3D MFString in JSON: I’ve let you know in email, telephone call and issue tracker that JSON MFString is documented on the following page, which we produced together. There are also thousands of X3D Examples
online that each include JSON encoding.<u></u><u></u></p>

<p class="MsoNormal">Are you now OK with what is stated and demonstrated regarding X3D MFString as JSON arrays of string type?<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Meanwhile it is not clear from the issue whether the entry is about JSON schema, X3dToJSON.xslt, MFString, JSON string, JSON string arrays, or what. Apologies but I’m not tracking your concern.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>

<p class="MsoNormal">Have tried reading tracker issue #10 a few times but am still not sure what the issue is asking. Now you are cross-threading the sourceforge issue tracker and the x3d-public mailing list... ouch. Color me “lost” on this one.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">You might be thinking about the use of an XML attribute without extra quotation marks, such as <Text string=’hey now’/> which is common. The Java and Python APIs are forgiving of such type mismatches, most of our XML-handling tools are,
ClassicVRML is forgiving, it will no doubt be explicit in each of next spec versions.<u></u><u></u></p>

<p class="MsoNormal">Please let’s dial it back and get focused.<u></u><u></u></p>
<ul style="margin-top:0in" type="disc">
<li style="margin-left:0in">An issue tracker is good for simple fixable issues: point out specific problem, give a repeatable example. If possible note reference and suggested solution.<u></u><u></u></li><li style="margin-left:0in">Mailing lists are good for announcements and general discussion.<u></u><u></u></li></ul>
