   8     This empty template for the xml:space attribute removes it from
   9     any element where it is found. Inkscape adds it automatically, but
  10     we don't rely on it, and it's been deprecated for a while:

  18     This rule replaces a <tspan> directly inside of a <text> with its
  19     contents. The "directly" part is important because we actually use
  20     tspans in one place, for the origin -> destination. We don't want
  21     to clobber THOSE tspans, but we can avoid it by putting them in a
  22     group (<g>).

  29     Then this rule matches everything, and copies it while applying
  30     any relevant templates to its children. Either we'll hit a <tspan>
  31     within a <text> and process it, or we'll hit this rule again.
