I MAY have found a bug. The validator at "http://validator.w3.org" does not like numerical attribute values. For example when validating: https://www.eyeasme.com/Joe/MathML/HTML5_MathML_browser_test.html Many attribute values are marked as "Bad value" The easiest ones to check are those attributes which can only be positive integers, for example "rowspan" and "columnspan". The validator complains about the line: <mtd columnspan="2"> with the message: Error: Bad value 2 for attribute columnspan on element mtd. >From line 1273, column 21; to line 1273, column 40 <mtd columnspan="2">↩ I checked the latest recommended MathML spec at: http://www.w3.org/TR/MathML2/chapter3.html#presm.mtd Section 3.5.4.2 Attributes and the latest MathML next generation spec at: http://www.w3.org/TR/2009/CR-MathML3-20091215/chapter3.html#presm.mtd Section 3.5.4.2 Attributes Both specify that the attributes "rowspan" and "columnspan" have positive integer values. Is this a bug or am I missing something? JoeReceived on Thursday, 20 May 2010 15:51:36 UTC
