SchematronSeveral standards bodies, including NIST in the USA, strongly recommend against ending the representation of a number with a decimal point. So instead of ‘3.’ use either ‘3’ or ‘3.0’.


<!-- WARNING: this constraint should be examining all elements and attributes whose value or content is defined with teidata.point. However, we have no easy access to that list (which would need to be generated dynamically), so instead it is looking at all @points attributes, which (as of this writing) is the only member of that list. I.e., if you add an attribute or element that uses (or change an existing one to use) teidata.pointer, you likely need to change the @context below to match. -->
