the setting used in css_parser.log.raiseExeptions is used

if comments should be added to CSS DOM or simply omitted
:param validate:
if parsing should validate, may be overwritten in parse methods

:param cssText:
CSS string to parse
:param encoding:
If ``None`` the encoding will be read from BOM or an @charset
rule or defaults to UTF-8.
If given overrides any found encoding including the ones for
imported sheets.
It also will be used to decode `cssText` if given as a (byte)
string.
:param href:
The ``href`` attribute to assign to the parsed style sheet.
Used to resolve other urls in the parsed sheet like @import hrefs.
:param media:
The ``media`` attribute to assign to the parsed style sheet
(may be a MediaList, list or a string).
:param title:
The ``title`` attribute to assign to the parsed style sheet.

(e.g. IOError).
:param filename:
of the CSS file to parse, if no `href` is given filename is
converted to a (file:) URL and set as ``href`` of resulting
stylesheet.
If `href` is given it is set as ``sheet.href``. Either way
``sheet.href`` is used to resolve e.g. stylesheet imports via
@import rules.
:param encoding:
Value ``None`` defaults to encoding detection via BOM or an
@charset rule.
Other values override detected encoding for the sheet at
`filename` including any imported sheets.

:param fetcher:
A function which gets a single parameter
``url``
the URL to read
and must return ``(encoding, content)`` where ``encoding`` is the
HTTP charset normally given via the Content-Type header (which may
simply omit the charset in which case ``encoding`` would be
``None``) and ``content`` being the string (or unicode) content.
The Mimetype should be 'text/css' but this has to be checked by the
fetcher itself (the default fetcher emits a warning if encountering
a different mimetype).
Calling ``setFetcher`` with ``fetcher=None`` resets css_parser
to use its default function.
