<p> tag in xdoc file is lost after <ul> tags encountered during transformation to HTML

When writing the xdoc sources for documentation, I add various HTML markup tags, notably the paragraph <p> character. After site generation, I find that the paragraph <p> character is stripped after a list tag such as <ul> is encountered.

I resort to using break <br> tags to separate all subsequent paragraph blocks after the list because no more paragraph <p> character appear in the source HTML

I have attached a simple xdoc format file that demonstrates the problem.
