# Restrictions

With the exception of minOccurs and maxOccurs, which are also listed in separate columns, the XML Schema restrictions listed in the Restrictions column are not enforced by filePro but are listed for the benefit of the developer. It is the responsibility of the developer to ensure that these restrictions are enforced.
The various types of restrictions that are applicable for each XML Schema data type, the syntax for those restrictions, and the meaning of those restrictions can be found in the XML Schema specification document at XML Schema Part 2: Data types Second Edition
