In a structured document, with sections, parts, and possibly subsections, is there a word, or prefix, or construction, to identify the introduction before a section or a subsection?
For instance, for the second subsection of section one, i.e. §1.2. one would write,
See Section 1, Subsection 2 for more details
What about the preamble/introduction of section 1?
1. Section One
This is preamble of the section 1.
1.1. Subsection 1
Text of subsection 1.1.
1.2. Subsection 2
Text of subsection 1.2.
