23812 2013-11-12 22:24:09 +0000 Validator says feComposite needs in2, implementations say it doesn't, and the spec doesn't seem to care either way. 2013-11-13 19:16:50 +0000 1 1 1 Unclassified Validator check HEAD All All NEW P2 major --- 1 aaron dave.null www-validator-cvs oldest_to_newest 96213 0 1414 aaron 2013-11-12 22:24:09 +0000 Created attachment 1414 An SVG which triggers the issue. I've noticed when running an svg through the validator, it tells me that in2 is a required attribute for feComposite. After reading the appropriate parts of the spec (http://www.w3.org/TR/SVG/filters.html#feCompositeIn2Attribute), it appears to be defined to inherit its default from `in', in which case it is not required, and has defined behaviour (namely considering the immediately preceding filter primitive's result to be the input). This seems to be the conclusion that implementors have drawn, since implementations handle it this way as well. As you can see though, it isn't that way according to the validator. http://validator.w3.org/unicorn/check?ucn_uri=magnifi.ca%2Fphotos%2Frnd%2Fdms_w3c.svg&tests=markup-validator&warning=1&profile=svg&usermedium=all&ucn_lang=en&ucn_task=custom# 1414 2013-11-12 22:24:09 +0000 2013-11-12 22:24:09 +0000 An SVG which triggers the issue. dms.svg image/svg+xml 2838 aaron PD94bWwgdmVyc2lvbj0iMS4wIiBlbmNvZGluZz0iVVRGLTgiIHN0YW5kYWxvbmU9Im5vIj8+Cjxz dmcgeG1sbnM9Imh0dHA6Ly93d3cudzMub3JnLzIwMDAvc3ZnIiB4bWxuczp4bGluaz0iaHR0cDov L3d3dy53My5vcmcvMTk5OS94bGluayIgd2lkdGg9Ijg2NCIgaGVpZ2h0PSI4NjQiPgogPGRlZnM+ CiAgPGxpbmVhckdyYWRpZW50IGlkPSJidWJibGVHcmFkaWVudCIgeDE9IjAiIHkxPSI3MiIgeDI9 IjAiIHkyPSI4NDYiIGdyYWRpZW50VW5pdHM9InVzZXJTcGFjZU9uVXNlIiBncmFkaWVudFRyYW5z Zm9ybT0idHJhbnNsYXRlKC04NjQsMCkiPgogICA8c3RvcCBzdG9wLWNvbG9yPSIjYTJkYjY3IiBv ZmZzZXQ9IjAiIC8+CiAgIDxzdG9wIHN0b3AtY29sb3I9IiM3ZGM3NGQiIG9mZnNldD0iMC4xMjUi IC8+CiAgIDxzdG9wIHN0b3AtY29sb3I9IiM2ZGJjNDUiIG9mZnNldD0iMC4yNSIgLz4KICAgPHN0 b3Agc3RvcC1jb2xvcj0iIzU3YjAzZCIgb2Zmc2V0PSIwLjUiIC8+CiAgIDxzdG9wIHN0b3AtY29s b3I9IiM0ZmE3MzYiIG9mZnNldD0iMSIgLz4KICA8L2xpbmVhckdyYWRpZW50PgogIDxmaWx0ZXIg aWQ9ImJ1YmJsZSI+CiAgIDxmZUZsb29kIGZsb29kLWNvbG9yPSIjMjQ3YTFiIiAvPgogICA8ZmVD b21wb3NpdGUgaW4yPSJTb3VyY2VHcmFwaGljIiBvcGVyYXRvcj0iaW4iIC8+CiAgIDxmZU9mZnNl dCBkeD0iMCIgZHk9IjciIHJlc3VsdD0ibyIgLz4KICAgPGZlR2F1c3NpYW5CbHVyIGluPSJTb3Vy Y2VHcmFwaGljIiBzdGREZXZpYXRpb249IjEuMiIgLz4KICAgPGZlQ29tcG9zaXRlIGluMj0ibyIg cmVzdWx0PSJjIiAvPgogICA8ZmVGbG9vZCBmbG9vZC1jb2xvcj0iI2Q1ZjliMiIgLz4KICAgPGZl Q29tcG9zaXRlIGluMj0iU291cmNlR3JhcGhpYyIgb3BlcmF0b3I9ImluIiAvPgogICA8ZmVPZmZz ZXQgZHk9Ii03IiBkeD0iMCIgLz4KICAgPGZlQ29tcG9zaXRlIGluPSJjIiByZXN1bHQ9ImMiIC8+ CiAgIDxmZUZsb29kIGZsb29kLWNvbG9yPSIjYzJlMzhiIiAvPgogICA8ZmVDb21wb3NpdGUgaW4y PSJTb3VyY2VHcmFwaGljIiBvcGVyYXRvcj0iaW4iIC8+CiAgIDxmZU9mZnNldCBkeD0iMCIgZHk9 Ii0xNCIgLz4KICAgPGZlQ29tcG9zaXRlIGluPSJjIiAvPgogIDwvZmlsdGVyPgogIDxmaWx0ZXIg aWQ9ImVtYmxlbSIgd2lkdGg9IjEuMiIgaGVpZ2h0PSIxLjMiIHg9Ii0uMSIgeT0iLS4xNSI+CiAg IDxmZUZsb29kIGZsb29kLWNvbG9yPSIjMDAwIiBmbG9vZC1vcGFjaXR5PSIwLjEiIC8+CiAgIDxm ZUNvbXBvc2l0ZSBpbjI9IlNvdXJjZUdyYXBoaWMiIG9wZXJhdG9yPSJpbiIgLz4KICAgPGZlT2Zm c2V0IGR5PSIzNiIgZHg9IjAiIC8+CiAgIDxmZUdhdXNzaWFuQmx1ciBzdGREZXZpYXRpb249IjE4 IiAvPgogICA8ZmVDb21wb3NpdGUgaW49IlNvdXJjZUdyYXBoaWMiIHJlc3VsdD0iYyIgLz4KICAg PGZlRmxvb2QgZmxvb2QtY29sb3I9IiMyNzg1MWIiIC8+CiAgIDxmZUNvbXBvc2l0ZSBpbjI9IlNv dXJjZUdyYXBoaWMiIG9wZXJhdG9yPSJpbiIgLz4KICAgPGZlR2F1c3NpYW5CbHVyIHN0ZERldmlh dGlvbj0iMyIgLz4KICAgPGZlQ29tcG9zaXRlIGluPSJjIiAvPgogIDwvZmlsdGVyPgogPC9kZWZz PgogPHBhdGggZD0iTTQzMiw3MzhjLTE4OC44ODE0LDAtMzQyLTE0OS4wODkxOC0zNDItMzMzczE1 My4xMTg2LTMzMywzNDItMzMzLDM0MiwxNDkuMDg5MTgsMzQyLDMzM2MwLDI5Ny0zMjQsNDQxLTM0 Miw0NDEiIGZpbGw9InVybCgjYnViYmxlR3JhZGllbnQpIiBmaWx0ZXI9InVybCgjYnViYmxlKSIg Lz4KIDxwYXRoIGQ9Ik00ODYsMjE2Yy0xNi45NTkyNSwwLTMyLjA2ODg3LDcuODMzOTEtNDEuOTY4 NzUsMjAuMDYyNS0zLjc2MjIxLTEuMzMzNjktNy44MTE5LTIuMDYyNS0xMi4wMzEyNS0yLjA2MjUt MTMuNDQ4NTMsMC0yNS4xNjMsNy4zODY4Ny0zMS4zNDM3NSwxOC4zMTI1LTEuNTI3LTAuMTk3NTct My4wNzU0NC0wLjMxMjUtNC42NTYyNS0wLjMxMjUtNy4yNjA5OSwwLTE0LjAwMTEsMi4xNzc0MS0x OS42NTYyNSw1Ljg3NS01LjI5NDQyLTE4Ljk2MTQtMjIuNjkzMjYtMzIuODc1LTQzLjM0Mzc1LTMy Ljg3NS0yNC44NTI4MSwwLTQ1LDIwLjE0NzE5LTQ1LDQ1djE4LDI3MGMwLDE5Ljk0NCwxNi4wNTYs MzYsMzYsMzZoMTgwYzE5Ljk0NCwwLDM2LTE2LjA1NiwzNi0zNnYtNTRoMzZjMTkuOTQ0LDAsMzYt MTYuMDU2LDM2LTM2di0xMDhjMC0xOS45NDQtMTYuMDU2LTM2LTM2LTM2aC0zNnYtMzYtMThjMC0y OS44MjMzOC0yNC4xNzY2Mi01NC01NC01NHptLTE2MiwxMDhoMTgwdjIxNmMwLDkuOTcyLTguMDI4 LDE4LTE4LDE4aC0xNDRjLTkuOTcyLDAtMTgtOC4wMjgtMTgtMTh2LTIxNnptMzUuNzE4NzUsMTcu NzE4NzVhMTguMDAxOCwxOC4wMDE4LDAsMCwwLC0xNy43MTg3NSwxOC4yODEyNXYxNjJhMTguMDAx OCwxOC4wMDE4LDAsMSwwLDM2LDB2LTE2MmExOC4wMDE4LDE4LjAwMTgsMCwwLDAsLTE4LjI4MTI1 LC0xOC4yODEyNXptNTQsMGExOC4wMDE4LDE4LjAwMTgsMCwwLDAsLTE3LjcxODc1LDE4LjI4MTI1 djE2MmExOC4wMDE4LDE4LjAwMTgsMCwxLDAsMzYsMHYtMTYyYTE4LjAwMTgsMTguMDAxOCwwLDAs MCwtMTguMjgxMjUsLTE4LjI4MTI1em01NCwwYTE4LjAwMTgsMTguMDAxOCwwLDAsMCwtMTcuNzE4 NzUsMTguMjgxMjV2MTYyYTE4LjAwMTgsMTguMDAxOCwwLDEsMCwzNiwwdi0xNjJhMTguMDAxOCwx OC4wMDE4LDAsMCwwLC0xOC4yODEyNSwtMTguMjgxMjV6bTcyLjI4MTI1LDE4LjI4MTI1aDE4Yzku OTcyLDAsMTgsOC4wMjgsMTgsMTh2NzJjMCw5Ljk3Mi04LjAyOCwxOC0xOCwxOGgtMTh2LTEwOHoi IGZpbGw9IiNmZmYiIGZpbHRlcj0idXJsKCNlbWJsZW0pIiAvPgo8L3N2Zz4K
