# Removes all block (and optionally span) level HTML tags from the element tree.

# This converter can be used on parsed HTML documents to get an element tree that will only
# contain native kramdown elements.
#
# *Note* that the returned element tree may not be fully conformant (i.e. the content models of
# *some elements may be violated)!
#
# This converter modifies the given tree in-place and returns it.
