1. The expression on the first line is identical to the one on the second
line.
2. "child::" is implicit.
To answer your question, $fpath will test true if it is not empty.
<xsl:for-each select="//FCR[$fpath and @fastPath=$fpath]/*[@nodeType=$rtype] |
//FCR[$fpath and @fastPath=$fpath]/*">
That will give you an FCR/* as long as $fpath is not empty.
If you want something when $fpath is empty, use //FCR[not($fpath)]...
