Erratum on xsl:apply-imports for XSLT 1.0 Rec

In XSLT 1.0, as amended through today, section 5.6 is overly terse about
the context that is in effect for xsl:apply-imports. It says that
apply-imports "processes the current node" but does not say that the
processing is exactly like apply-templates other than the choice of
templates. A Xalan user questioned the behavior of position() within the
template invoked by apply-imports, and I cannot say definitively that the
context position and size are the same as for the template containing the
apply-imports instruction. Please clarify the required behavior through an
erratum.
