According to spec, http://www.w3.org/TR/xsl11/, region-name can have one of
default values or any custom value:
{code}
7.27.17 "region-name"
XSL Definition:
Value: xsl-region-body | xsl-region-start | xsl-region-end | xsl-region-before
| xsl-region-after | <name>
Initial: see prose
Inherited: no, a value is required
Percentages: N/A
Media: visual
Values have the following meanings:
xsl-region-body
Reserved region-name for use as the default name of fo:region-body. This
name may not be used on any other class of region.
xsl-region-start
Reserved region-name for use as the default name of fo:region-start. This
name may not be used on any other class of region.
xsl-region-end
Reserved region-name for use as the default name of fo:region-end. This
name may not be used on any other class of region.
xsl-region-before
Reserved region-name for use as the default name of fo:region-before. This
name may not be used on any other class of region.
xsl-region-after
Reserved region-name for use as the default name of fo:region-after. This
name may not be used on any other class of region.
<name>
Names used as identifiers must be unique within a page-master.
This property is used to identify a region within a simple-page-master.
The "region-name" may be used to differentiate a region that lies on a
page-master for an odd page from a region that lies on a page-master for an
even page. In this usage, once a name is used for a specific class of region
(start, end, before, after, or body), that name may only be used for regions of
the same class in any other page-master. The reserved names may only be used in
the manner described above.
{code}
As 'region-name' property can be customized or be different from default
'xsl-region-body' it's better to to defer the processing of the
StartPageSequence to the moment when 'region-name' is defined.
