Subject: [PATCH 1/2] Import and export character case transformations
 unconditionally to/from HTML

Import small caps and export small caps, lowecase, uppercase and titlecase
transformations unconditionally to/from HTML. Previously import and export
was limited by browser compatibility settings but all mainstream browsers
released within last 5 years or so should support the relevant CSS attributes.
