# Each MultiXml parser is expected to parse an XML document into a Hash. The
# conversion rules are:
#
# - Each document starts out as an empty Hash.
#
# - Reading an element created an entry in the parent Hash that has a key of
# the element name and a value of a Hash with attributes as key value
# pairs. Children are added as described by this rule.
#
# - Text and CDATE is stored in the parent element Hash with a key of
# '__content__' and a value of the text itself.
#
# - If a key already exists in the Hash then the value associated with the key
# is converted to an Array with the old and new value in it.
#
# - Other elements such as the xml prolog, doctype, and comments are ignored.
