>          Issue Type: Bug
>          Components: OData JSON CSDL

> JSON Schema offers the keywords minimum, maximum, and multipleOf for fine-tuning the value range of numeric properties.
> While it is possible to translate Precision="5" and Scale="2" into
> - multipleOf: 1e-2
> - minimum: -999.99
> - maximum: 999.99
> it is rather hard for an OData client to re-engineer the precision and scale
> Similar for temporal values: here Precision="7" would have to be -translated into a regular expression
> - "pattern":"(^[^.]*$|[.][0-9]{1,7}$)"
> We could add the original scale and precision as extension keywords.
> And we could additonally opt to omit the rather cryptic JSON Schema representation that would only benefit JSON Schema validators.
