RE: DOCBOOK-APPS: formal.procedures and insert.xref.page.number andfont size in xsls

[David Cramer <david_cramer@broadjump.com>]

Looks like you have to adjust the params region.before.extent and
region.after.exten along with the font size.

Using the following settings, the errors go away and the page number's
come back:
<xsl:param name="body.font.master">11</xsl:param>
<xsl:param name="region.after.extent" select="'14pt'"/>
<xsl:param name="region.before.extent" select="'14pt'"/>

Here's Nikolai Grigoriev's explanation in reply to a question and sample
file I sent him:

XEP works as expected. Let's see:

- extents of both region-before and region-after in your document are 12
pt;
- the line height is not defined, therefore a default of (1.2 *
font-size) is
used
  (as prescribed by the spec);
- therefore, the maximum font size to fit a line of text (with half
leadings
around
   it) into the avaliable space is: 12 pt / 1.2 = 10 pt. On bigger font
sizes,
there is
   no room to fit even a single line


To repair, you should either increase extents of side regions to a value
larger
than the computed value of line-height, or set line-height to a smaller
value:

<fo:block font-size="10pt" line-height="1">....

or by using a CSS shorthand:

<fo:block font="10pt/1 Futura">....

By the way: in your code, I see specifications like font-size="10"
(without
any measurement unit). This is unreliable: we give no guarantee of
consistent
treating of unitless lengths. You should better avoid it.
