[EXI] Options Document Schema not clear

Hi EXI WG,

       1) In the options document schema why precompress is a separate
element. The alignment value can be "bitpacked", "byte-aligned" or
"precompression" as per the specification. 

2) Also many of the elements take values of ComplexType though they take
some string or boolean value. 

3) The use of strict element is not explained anywhere in the spec.

Some examples for the options document can be useful in understanding.
Please help me with this ambiguities.

 

Regards
