T.structureInfo()

A heading is a tuple of pairs (node type, feature value)
	of node types and features that have been configured as structural elements
These 3 structural elements have been configured
	node type book       with heading feature book
	node type chapter    with heading feature chapter
	node type verse      with heading feature verse
You can get them as a tuple with T.headings.

Structure API:
	T.structure(node=None)       gives the structure below node, or everything if node is None
	T.structurePretty(node=None) prints the structure below node, or everything if node is None
	T.top()                      gives all top-level nodes
	T.up(node)                   gives the (immediate) parent node
	T.down(node)                 gives the (immediate) children nodes
	T.headingFromNode(node)      gives the heading of a node
	T.nodeFromHeading(heading)   gives the node of a heading
	T.ndFromHd                   complete mapping from headings to nodes
	T.hdFromNd                   complete mapping from nodes to headings
	T.hdMult are all headings    with their nodes that occur multiple times

There are 8231 structural elements in the dataset.

T.structureInfo()

A heading is a tuple of pairs (node type, feature value)
	of node types and features that have been configured as structural elements
These 3 structural elements have been configured
	node type book       with heading feature book
	node type chapter    with heading feature chapter
	node type verse      with heading feature verse
You can get them as a tuple with T.headings.

Structure API:
	T.structure(node=None)       gives the structure below node, or everything if node is None
	T.structurePretty(node=None) prints the structure below node, or everything if node is None
	T.top()                      gives all top-level nodes
	T.up(node)                   gives the (immediate) parent node
	T.down(node)                 gives the (immediate) children nodes
	T.headingFromNode(node)      gives the heading of a node
	T.nodeFromHeading(heading)   gives the node of a heading
	T.ndFromHd                   complete mapping from headings to nodes
	T.hdFromNd                   complete mapping from nodes to headings
	T.hdMult are all headings    with their nodes that occur multiple times

There are 8230 structural elements in the dataset.

Conclusion: duplicate structure problem resolved with new release.
