No, it's not currently possible with standard processors.  The difference is 
that you were creating a Result Tree Fragment (RTF), which is not the same as 
a node-set.

All you can do with an RTF is <xsl:copy-of/> and <xsl:value-of/>.  The idea is 
(was) that you can create an RTF as the value of a variable and re-use it 
throughout your stylesheet.  For example, in HTML you might have some special 
code to output a bullet point with pretty graphics, and you want to re-use 
that code with the exact same <img> tag.

You cannot select children of an RTF.  To do that, you have to convert it to a 
node-set.  Processor designers realized the pain of doing this, so they 
provide xxx:node-set() functions to do the conversion.  Unfortunately, the 
functions are not compatible between processors, so you will have to do some 
tricks if you want to use more than one processor.

Well, go complain to the XSLT 1.0 designers :).  XSLT 2.0 doesn't have this 
problem, since so many people like yourself have complained.

I believe that Saxon 7.0 is the only browser that supports XSLT 2.0.  You can 
go try that, get RTF to node-set conversion, and a bunch of other new 
features for free.
