# The Transitive formatter writes an XML document that parses to an
|
|
# identical document as the source document. This means that no extra
|
|
# whitespace nodes are inserted, and whitespace within text nodes is
|
|
# preserved. Within these constraints, the document is pretty-printed,
|
|
# with whitespace inserted into the metadata to introduce formatting.
|
|
#
|
|
# Note that this is only useful if the original XML is not already
|
|
# formatted. Since this formatter does not alter whitespace nodes, the
|
|
# results of formatting already formatted XML will be odd.
