You could also use the union operator, or its short form |, as in
(foo | *[descendant::foo | descendant::bar])[1]
In contrast to the sequence operator (the comma), it will eliminate
duplicates and return its results in document order.

I answer both questions to myself:
<xsl:sequence="*[local-name() eq 'foo' or descendant::foo or

(unless I got something wrong again).
Please, excuse me for the noise.

I now see that, on top of that, I am adding duplicate copies of nodes
that match both conditions to the sequence (-_-;). I would also
appreciate a hint on how to make that selection without dupes.

I'd like to select the first child of the current node that either:
1. is a "foo" element
2. has "foo" or "bar" descendant(s)
The following sequence returns me all nodes matching either or both of
those conditions:
<xsl:sequence select="foo, *[descendant::foo, descendant::bar]"/>
but not necessarily ordered according to their position as children of
the current node. As a result, the first element in that sequence,
selected like this:
<xsl:sequence select="(foo, *[descendant::foo, descendant::bar])[1]"/>
is not necessarily the first matching child of the current node.
How do I sort elements in that sequence according to their position as
children of the current context, so that the first element in that
sequence is actually the first matching child in the current node?
