FORMAT/CNL example has Number=G, should be Number=. ?

[eroller]

The FORMAT/CNL field has Number=G according to:

hts-specs/VCFv4.5.tex

Line 1149 in a6a4504

##FORMAT=<ID=CNL,Number=G,Type=Float,Description="Copy number genotype likelihood">

but the field as described below seems to be in conflict:

hts-specs/VCFv4.5.tex

Line 1160 in a6a4504

CNL specifies a list of $log_{10}$ likelihoods for each potential copy number, starting from zero.

I think the Number=G means the number of possible GT values that can be formed from the alleles (REF and ALT)? When using allele specific copy number alleles then there may be more than one possible GT for a given total copy number value.

Perhaps the Number=G should be changed to Number=.? And the same would go for CNP?
