Between 1 and 2 there is know different.

normalize-space() on an "empty" element returns an empty string. A 
text-node without any non-whitespace character will be removed 
completely using normalize-space(). So the test

<xsl:when test="normalize-space()">

is enough.

Whitespaces can be removed as far as I know.

This is only for the XML, not the XSLT.

The best thing is to use the non-breaking space character, which won't 
be removed. In XML/Unicode it's & #160; :

<fo:inline white-space-collapse="false">& #160;</fo:inline>
