Please don't do this. That's an abuse of the semantics of text, akin to the malpractice in HTML of tagging a word or phrase as 'h1' when it's not a heading, just to get the display, font-size, and styling of an 'h1'. If a relative positioning system is desireable for SVG (and it is), let it be put into the Spec and implemented. That way, you could declaratively get such relative positioning for free.
There is one way of doing this that is valid: you could actually give real semantic values to the bar, by creating an SVGFont with ligature glyphs for the number character characters, and giving each a certain height. For instance, a glyph for '2' and '3' (in that order) would represent the value for 23 when using that font. That way, someone using alternate presentation (such as a DOM-scraping voice browser) or copying the text on the screen would get the proper value for the bar. In fact, that would be rather neat, since searching for a text string would highlight that bar. However, if you have large range of values, or floating point values, creating the font would be rather intensive.
