Description Vitaliy 2015-03-11 10:43:00 UTC 
Specification defines how to setup focus for evaluation of the sequence constructor in the xsl:merge-action element:

"The context item is the first item in the current group, that is current-group()[1]"

https://www.w3.org/XML/Group/qtspecs/specifications/xslt-30/html/Overview-diff.html#element-merge-action

It looks like fn:current-group() function is used together with xsl:for-each-group instruction, but not with xsl:merge. 
I believe that fn:current-merge-group() must be used instead.

The WG today accepted the correction and it has been applied to the spec.
