Independance of parameters in header

Description:

The profile may advertise profile options in the header as xsd:decimal value.
http://www.w3.org/TR/2012/WD-exi-profile-20120410/#headerIntegration

1. The localValuePartitions parameter is encoded as the sign of the decimal value
2. The maximumNumberOfBuiltInElementGrammars parameter is represented by the first unsigned integer +1
3. The maximumNumberOfBuiltInProductions parameter is represented by the second unsigned integer +1

Currently there is no possibility to account for the use case that the localValuePartitions parameter is set while having no mentioning about the other two "undefined" parameters.

Some wg members believe that having the possibility to set a value to undefined/not-set may be useful and does not hurt compactness. One proposal is to use the following strategy for unsigned integers

0 ... unbounded (EXI 1.0 spec behavior)
1 ... undefined/not-set (e.g, use out-of-bound knowledge for this parameter)
n+2 ... where n is the actual value for this parameter
