Because it defines the syntax of a language with literal values, the ADQL spec 
does explicitly specify how numbers can be expressed... so there is a 
precedent for individual specs to do this.

In general I agree that all those examples should work, including scientific 
notation. 

PS-I don't think the extra letter on the end that some languages permit 
(sometimes require) to tell the compiler the data type of a primitive (e.g. 
1000L for long as opposed to int) should be permitted/used.
