DOCBOOK-APPS: 1.52.1 xsl, font-family problem

I upgraded my docbook xsl stylesheets from 1.50.0 to 1.52.1 and am getting a number of new errors.

Here's what's produced at the beginning of the fo doc by 1.50.0 (and also 1.51.1):

<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format" line-height="normal" text-align="justify" font-size="10pt" font-family="Times Roman" language="en">

Here's what is produced by 1.52.1:

<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format" line-height="normal" text-align="justify" font-size="10pt" font-family="&quot;Times Roman&quot;,serif" language="en">

I think the use of the entity &quot following the " char is causing problems.

Now I get the following error when processing with either FOP 0.20.3 or 0.20.4:

[ERROR]: unknown font "Times Roman",serif,normal,normal so defaulted font to any
[ERROR]: defaulted font to any,normal,normal
