The "Target when no doctype found: HTML5" seems to be broke or corrupted for content pages that serve master pages. When I try to open web form pages in the designer, I get the "Cannot complete action..." dialog box over and over. However, if I change
the Validation "target" to any value less than HTML5, the pages load. But now I get swigglies under the "html5-type" attributes.
I've tried repairing VS and no good.
Is there another trick to fixing the corrupted HTML5 schema definition file?
