Support for Paragraph before and after auto spacing
w:beforeAutospacing="1" w:after="100" w:afterAutospacing="1"
w:line="240" w:lineRule="auto" />
Specifies whether a consumer shall automatically determine
the spacing before this paragraph based on its contents.
This automatic spacing shall match the spacing which would
be applied to the paragraph in an HTML document where no explicit spacing
before/after is specified.
If this attribute is specified, then any value in before
or beforeLines is ignored, and the spacing is automatically
determined by the consumer.
