NVD reported a problem with section headers not having the book title capitalized; actually it seems she meant italicized, but when I checked, one of the instances had the requisite <title> tag and the other one didn't, but neither was showing up as italicized. I discovered that at the <head> tag level, I was just doing <xsl:value-of> instead of <xsl:apply-templates>, so I fixed that in both the XHTML and PDF rendering code, and it now looks right. We should watch out for any side-effects on older documents resulting from this, but I think the worst that could happen would be effectively corrections.
