The **BaseElement** is the root for all SVG elements. The SVG attributes
are stored in **attribs**, and the SVG subelements are stored in
**elements**.

:param extra: extra SVG attributes (keyword arguments)
* add trailing '_' to reserved keywords: ``'class_'``, ``'from_'``
* replace inner '-' by '_': ``'stroke_width'``
SVG attribute names will be checked, if **debug** is `True`.
workaround for removed **attribs** parameter in Version 0.2.2::
# replace
element = BaseElement(attribs=adict)
#by
element = BaseElement()
element.update(adict)
