SIAP and encoding of POS input parameter

[Doug Tody]

And here is the reference:

     http://www.w3.org/TR/xmlschema-2/#double

An excerpt:

     The canonical representation for float is defined by
     prohibiting certain options from the Lexical representation
     (§3.2.4.1). Specifically, the exponent must be indicated by
     "E". Leading zeroes and the preceding optional "+" sign are
     prohibited in the exponent. If the exponent is zero, it must be
     indicated by "E0". For the mantissa, the preceding optional "+"
     sign is prohibited and the decimal point is required.
