That is what RCC was for and is what sXBL is for - using a richer more abstract semantic tag set and then providing an SVG visualization of it without mucking up the DOM of the other tagset.

(The PDF term DW> for this overlay is "tagged PDF".) Yes, it groups text elements that have been split to do kerning, a common fault of PDF in the wild. This is why SVG has tspan with many attributes to allow precise positioning, and requires that all text in a text element plus associated tspan children is selectable as a single unit. -- Chris Lilley mailto:chris@w3.org Chair, W3C SVG Working Group Member, W3C Technical Architecture Group
