2.1.252 Part 4 Section 2.7.4.5, rPrDefault (Default Run Properties)

WordPad supports this element. When the document is loaded, WordPad processes this element in the same way as a character style with the w:default attribute enabled. In the case where both the <rPrDefault> element and a character style with the w:default attribute enabled are present, the style definition that comes last is used for obtaining the default character properties. When the document is saved, WordPad does not write out this element.
