Let us say that I have a subtree like

<author>
<first>Priscilla</first>
<last>Walmsley</last>
</author>

Using Saxon HE 9-3-0-4j and assuming the current node is the parent of
author, the result of

<xsl:value-of select="author" separator=" "/>

or

<xsl:value-of select="author" separator="' '"/>

is the same as

<xsl:value-of select="author"/>

that is, 'PriscillaWalmsley'.

PS In case this is not a totally stupid question, here is my complete
example.
