 * With the W3 Validator, I’m getting 9 errors related to ampersands in the CSS 
   generated by SAFE-CSS
 * > Warning Line 126, Column 76: cannot generate system identifier for general 
   > entity “csblog”

 * Is that to be expected? Is there anything I can do to change the encoding to 
   resolve this problem?

 * Switched back to Simple CSS, just for now. No versioning, but the ampersands 
   are escaped.
