[xsl] Can an XSLT 3.0 stylesheet access the complete sequence of values passed in as the initial match selection?

2020-01-12 05:32:29

In https://www.w3.org/TR/xslt-30/#dt-initial-match-selection, the XSLT 3
spec outlines:

   A stylesheet may be evaluated by supplying a value to be processed,
   together with aninitial mode
   <https://www.w3.org/TR/xslt-30/#dt-initial-mode>. The value (which
   can be any sequence of items) is referred to as the*initial match
   selection*.

and

   specifically, each item in the input sequence is processed by
   selecting and evaluating the best matching template rule


Does a stylesheet have any way of accessing the whole sequence? Or is it
only able to process each item in the sequence with a matching template?

For instance, if the initial match selection is a sequence of array
items, is there any way to merge those arrays? The function array:join
https://www.w3.org/TR/xpath-functions/#func-array-join can join a
sequence of arrays, but is there any way in that case of the initial
match selection being a sequence of arrays to apply it to that initial
match selection?
