Okay, I managed to get the double.sided param to work with PassiveTeX, but
(1) I'm not quite sure how I did it and (2) I still have a few problems
with the results.
(1) The solution that makes no sense to me:
I noticed that the error PassiveTeX was crashing on had something to do
with the section.heading space-before parameters. Rather than writing in a
new section.title.properties attribute-set, I thought I'd just test this
theory with an existing (but commented out) fix from pre-DocBook XSL 1.52.
Back then, I was having trouble with the fact that the section.heading was
relying on the keep-with-next.within-column attribute of the section
template, an inheritance which PassiveTeX refused to pass on. My
customization to correct this was
<xsl:template name="section.heading">
<xsl:param name="level">1</xsl:param>
<xsl:param name="title"></xsl:param>
<xsl:variable name="fsize">
<xsl:choose>
<xsl:when test="$level=1">18</xsl:when>
<xsl:when test="$level=2">16</xsl:when>
<xsl:when test="$level=3">14</xsl:when>
<xsl:when test="$level=4">12</xsl:when>
<xsl:when test="$level=5">12</xsl:when>
<xsl:otherwise>10</xsl:otherwise>
</xsl:choose>
</xsl:variable>
<fo:block keep-with-next.within-column="always"
font-size="{$fsize}pt"
font-weight="bold"
font-family="{$title.font.family}"
margin-left="4pc"
text-indent="-4pc"
space-before.minimum="1em"
space-before.optimum="1.5em"
space-before.maximum="2em">
<xsl:copy-of select="$title"/>
</fo:block>
</xsl:template>
After 1.52, the section.title.properties addition to param.xsl included
the keep-with-next, so I commented this out. Now, in order to test the
space-before measurement, I un-commented this section. Then I set the
double.sided param to one and ran my document through xsltproc and
PassiveTeX. It worked.
Okay, so I figure this vindicates my reading of the error log. I commented
the fix out again, and added the following to my customization file:
<xsl:attribute-set name="section.title.properties">
<xsl:attribute name="font-family">
<xsl:value-of select="$title.font.family"/>
</xsl:attribute>
<xsl:attribute name="font-weight">bold</xsl:attribute>
<!-- font size is calculated dynamically by section.heading template -->
<xsl:attribute name
="keep-with-next.within-column">always</xsl:attribute>
<xsl:attribute name="space-before.minimum">1em</xsl:attribute>
<xsl:attribute name="space-before.optimum">1.2em</xsl:attribute>
<xsl:attribute name="space-before.maximum">2em</xsl:attribute>
</xsl:attribute-set>
This didn't work. Once again, PassiveTeX refused to process the FO,
claiming it was overruning on the space-before-maximum setting of 1.2em
(this also baffles me: 1.2 causes an overrun, but 2 works). I tried
setting this parameter directly in my param.xsl file. Still no luck. Where
is it getting the space-before.maximum value of 1.2 em? Yet when I
reactivate the customization for section.heading, it works.
(2) The problems
Okay, "works" is a relative term. I get the double-sided output from
PassiveTeX. Chapters all begin on odd-numbered pages, chapters ending on
an odd-numbered page are followed by a blank page, and the page numbers
are appropriately positioned to the left or right. My headers, however,
have disappeared (okay, it appears once, on a page in the table of
contents). Page numbers do not appear on blank pages or the first page of
a chapter. I have the headers.on.blank.pages and footers.on.blank.pages
params set to 1, but setting them to zero seems to have no effect.
Dazed and confused.
