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.
