          Return true if the attributes matches in attribute filter.
  
          An attribute filter is a dictionary containing: {attribute_name: value}.
          This function will return True if and only if all attributes have the same value.
          This function allows to set the dictionary via kwargs, thus you can filter like this:
  
          example::
              a.is_tag_matched(tag, name="foobar", other="barfoo")
  
          This function uses a fallback for attribute searching. It will by default use
          the namespace variant but fall back to the non-namespace variant.
          Thus specifiying :code:`{"name": "foobar"}` will match on :code:`<bla name="foobar" \>`
          as well as on :code:`<bla android:name="foobar" \>`.
  
          :param lxml.etree.Element tag: specify the tag element
          :param attribute_filter: specify the attribute filter as dictionary
