[xsl] xsl:if with "and' in test expression triggers error when running in xslt 2.0 mode?

[Taras Tielkes <taras@xxxxxxx>]

Hi,

Source document structure is
/doc
	/line
	/line
	...

My stylesheet contains some code to group these lines into a 3-column table.
Along the way some cleanup is done:
1) no rows will be inserted if all the cells are empty
2) the last row will not be inserted if it contains less than 3 cells.

Running the stylesheet quoted below in Saxon 7.5.1 triggers the error:
"A sequence of more than one item is not allowed here" at the line
containing the xsl:if element.

When I set the version attribute to "1.0" the sheet seems to work fine.

What makes ik fail when running in xslt 2.0 mode?

Thanks,

tt
