  === Notes ===
  
- XSD (XML Schema Part 2: Datatypes Second Edition) provides a mechanism to define "Constraining Facets" http://www.w3.org/TR/xmlschema-2/#rf-facets that may provide some solution for this requirement, at least at the schema level. '''[[FS-''' A proposal: Write not "at least at the schema level.", but "at the schema level. At the instance level, Schematron [http://www.schematron.com/] could be used for the same purpose."''']]'''
+ XSD (XML Schema Part 2: Datatypes Second Edition) provides a mechanism to define "Constraining Facets" http://www.w3.org/TR/xmlschema-2/#rf-facets that may provide some solution for this requirement at the schema level.

  Sometimes the constraint may need to be expressed using units different from the unit used in the document. For example, the maximum length of a string may need to be expressed in byte or pixels, or display cells instead of characters. This may lead to the need for quite a few parameters with the constraint (e.g. the encoding to use, or the font and point-size information, etc.)
