17.3.1.24 pBdr
This element specifies the borders for the parent paragraph. Each child element shall specify a specific kind of border (left, right, bottom, top, and between).
If this element is omitted on a given paragraph, its value is determined by the setting previously set at any level of the style hierarchy (i.e. that previous setting remains unchanged). If this setting is never specified in the style hierarchy, then no paragraph borders shall be applied.
[Example: Consider a pairing of paragraphs which have a three point red border around them, and a six point border between them. These paragraphs would each have the following set of paragraph borders:
<w:pBdr>
<w:top w:val="single" w:sz="24" w:space="1" w:color="FF0000" />
<w:left w:val="single" w:sz="24" w:space="4" w:color="FF0000" />
<w:bottom w:val="single" w:sz="24" w:space="1" w:color="FF0000" />
<w:right w:val="single" w:sz="24" w:space="4" w:color="FF0000" />
<w:between w:val="single" w:sz="48" w:space="1" w:color="4D5D2C" />
</w:pBdr>
The resulting paragraphs have identical pBdr values, therefore they would use the top, left, bottom, and right borders around them as a units, and the between border between each other. This matching heuristic is further discussed in the child elements of the pBdr element. end example]
