	 * There can be a body level sectPr.
	 * 
	 * Other sectPr are typically in a top level paragraph.
	 * 
	 * They can also be in a rich text content control.
	 * 
	 * (Word won't let you copy/paste a sectPr into a table cell.
	 *  And if you put one there in the XML, on opening, Word will
	 *  display the table, but gets a bit confused - it may show it
	 *  twice the second time on a separate page.  On save, the 
	 *  sectPr will be retained.  If you put the sectPr in a
	 *  content control in a tc, the behaviour is similar.  )
	 *  
	 * If you put a sectPr in a text box, Word can open the
	 * docx, and shows it as a page break.   But trying to 
	 * do that from within the Word UI results in:
	 * "You cannot put section breaks into a header, footer,
	 *  footnote, endnote, comment, text box, callout, or macro."
	 * 
	 * Based on the above, this finder looks for the sectPr
	 * only:
	 * - body level sectPr
	 * - top level P
	 * - inside a p in a content control (but not in a 
	 *   table)
