+These elements hold a single value of the indicated type. <sgmltag>bool</>
+elements hold either true or false. An important limitation exists in
+the parsing of floating point numbers -- fontconfig requires that
+the mantissa start with a digit, not a decimal point, so insert a leading
+zero for purely fractional values (e.g. use 0.5 instead of .5 and -0.5
+instead of -.5).
