5.10.4 from-page-master-region discrepancy?

[Glenn Adams]

In XSL-FO 1.1, 5.10.4, appears:

"If this function is used in an expression on a formatting object, F, that
is a descendant of an fo:page-sequence, then the computed value is taken
from the region specification that was used to generate the nearest
ancestor region reference area which has as its descendants the areas
returned by F."

However, this is followed by an example where "this function"
(from-page-master-region) is used on fo:page-sequence, and not a descendant
of fo:page-sequence!

<fo:page-sequence master-name="default-sequence"
writing-mode="from-page-master-region()">


How is this example to be reconciled with the normative language cited
above about being "used in an expression ... that is a descendant of an
fo:page-sequence"?

Glenn

I may be misreading, but since a page-sequence is not a descendant of a page-sequence, doesn’t the paragraph before the one you cited cover this situation?

The computed value of the designated property is taken from that property on the layout formatting object being used to generate the region viewport/reference area pair.

In other words, the value comes from the simple-page-master called all-pages.

No, I don't believe so: simple-page-master does not generate any area. It
is page-sequence which generates the region viewport/reference pairs.
