Defines the amount of white space in points, that will appear before and after each paragraph in Windows Help, and also allows you to set the spacing between individual lines within that paragraph.
Tip: You should never leave empty paragraphs between text to give the effect of white space, instead you should set this space using the spacing.
The HelpParaAfter element corresponds to the "(Spacing) Line-spacing" field, on the Paragraph sub-tab, on the Windows Help tab, of the Style object.
