Dear XML Schema Working Group.

With reference to the new W3C XSD 1.1 I want to write you, that we at SAP are
using decimal floating numbers and we are interested in all standards which
help to make xs:precisionDecimal usable and interchangeable.

We are using two formats:
•     “DECFLOAT34”
   This type can hold up to 34 decimal mantissa digits. The possible values
range from 1E-6143 through 9.999999999999999999999999999999999E+6144 plus the
corresponding negative values and zero. Such a number occupies 16 bytes. 

•     “DECFLOAT16”
   This is the smaller variant of the decimal floating-point types. It allows
up to 16 decimal mantissa digits and values in the range from 1E-383 through
9.999999999999999E+384 plus negative values and zero. This type needs 8 bytes.
