Hi Bernhard,
Actually,
a figure does not have to be confined to one page. That is a
stylesheet feature, not a feature of DocBook XML.
In DocBook XSL, a figure element is processed to use the attribute-set named 'figure.properties', which by default is defined in fo/param.xsl as:
<xsl:attribute-set name="figure.properties" use-attribute-sets="formal.object.properties"/>
In other words, it inherits the attributes set in 'formal.object.properties', and one of those attributes is:
<xsl:attribute name="keep-together.within-column">always</xsl:attribute>
It is this setting that tries to keep a figure to one page, which in most cases is what users want. However, a customization can change that behavior. For example:
<xsl:attribute-set name="figure.properties">
<xsl:attribute name="keep-together.within-column">
<xsl:choose>
<xsl:when test="count(d:mediaobject) >
1">inherit</xsl:when>
<xsl:otherwise>always</xsl:otherwise>
</xsl:choose>
</xsl:attribute>
</xsl:attribute-set>
This is an example of overriding one xsl:attribute in an
attribute-set. It also shows how the attribute-set is applied
separately to each instance of figure, so you can count
d:mediaobjects and relax the keep-together for those instances.
These two sections in my book illustrate this method of
customization:

Hi Bob,
unfortunately, your suggestion did not work. Obviously a figure is glued to one page, it cannot be spread on more than one. Therefore, the only thing that comes to my mind would be to reset the figure number by -1. Is this possible?
Regards
Bernhard

Hi Bernhard,
This is more of a DocBook issue than an Oxygen XML issue.
Currently DocBook 5.1 does not support subfigures, but version 5.2 under development will support a new element named <formalgroup> which can contain one or more "formal" elements (table, figure, example, equation). That would allow for subfigures. However, there is currently no release date for DocBook 5.2, nor do the stylesheets support that element yet.
For the current releases, I can only suggest a workaround. Put two mediaobjects in a figure element (they are allowed), and give each mediaobject a <caption> element whose para includes "a." or "b." and include subtitles there if needed. Maybe someone else has a better suggestion.

The Docbook definitive Guide does not mention subfigures. The Docbook xsl complete Guide does not either. I have a figure too large that the text can only be read by magnifying glass. So I wand two parts of it on two pages. But I cannot see how to number it correctly Fig. 1a and Fig. 1b. Can please point me in correct direction? Many thanks Bernhard
