It's so much clearer if you use literal result elements: <cover-body>
instead of <xsl:element name="cover-body">.

The XPath expression "for $x in EXPR return $x" can always be rewritten
"EXPR". You just want

<xsl:for-each select="collection(....)">

> 				<xsl:variable name="a" 
> select="document(document-uri(/))"/>

That's equivalent to <xsl:variable name="a" select="."/>

xsl:value-of takes the selected nodes (all the given-names) and outputs
their values, space-separated. So you have asked for all the given-names,
space-separated, then all the surnames, space-separated. What you want is
this:

<author>
  <xsl:for-each select="$a/article/head/author-group/author">
    <xsl:value-of select="given-name, surname"/>
  </xsl:for-each>
</author>

perhaps with some added punctuation or markup.
