Introduced in SpecsIntact Version 4.5.0, this feature automatically generates the Subpart Numbers for Numeric and  Alphanumeric Formatted Sections by placing the correct Subpart Numbers between the Subpart  <SPT> and the Title <TTL> tags.  Unlike the Traditional Paragraph Numbering the number within the Subpart Tag  and the auto generated Title number will always match.  This provides the capability to easily switch numbering schemes regardless of the original setup.
