constraints.checkMaximum

Specifies a maximum value for a field. This is different to <code>maxLength</code> which checks the number of items in the value. 
A maximum value constraint checks whether a field value is equal to or less than the specified value. 
The range checking depends on the type of the field. E.g. an integer field may have a maximum value of 100.
If a maximum value constraint is specified then the field descriptor <code>MUST</code> contain a type key.

Allows to work with 'Table Schema' (<https://specs.frictionlessdata.io/table-schema/>). 'Table Schema' is well suited for use cases around handling and validating tabular data in text formats such as 'csv', but its utility extends well beyond this core usage, towards a range of applications where data benefits from a portable schema format. The 'tableschema.r' package can load and validate any table schema descriptor, allow the creation and modification of descriptors, expose methods for reading and streaming data that conforms to a 'Table Schema' via the 'Tabular Data Resource' abstraction.
