	2008	* Cross-reference user-friendly V-Card entry labels to vCard XML tags
	2009	* and attributes.
	2010	*
	2011	* Order is (or should be) unimportant. For example: we have no way of
	2012	* knowing in what order real data will arrive.
	2013	*
	2014	* Format: Label, Pre-set text, "visible" flag, "editable" flag, XML tag
	2015	* name, XML tag's parent tag "path" (relative to vCard node).
	2016	*
	2017	* List is terminated by a NULL label pointer.
	2018	*
	2019	* Entries with no label text, but with XML tag and parent tag
	2020	* entries, are used by V-Card XML construction routines to
	2021	* "automagically" construct the appropriate XML node tree.
	2022	*
	2023	* Thoughts on future direction/expansion
	2024	*
	2025	* This is a "simple" vCard.
	2026	*
	2027	* It is possible for nodes other than the "vCard" node to have
	2028	* attributes. Should that prove necessary/desirable, add an
	2029	* "attributes" pointer to the vcard_template struct, create the
	2030	* necessary tag_attr structs, and add 'em to the vcard_dflt_data
	2031	* array.
	2032	*
	2033	* The above changes will (obviously) require changes to the vCard
	2034	* construction routines.
