<xsl:value-of select="$aname" /> <!-- The problem is here
	
When there are two primary keys is only print the name of the first
attribute. I can print for the first attribute key aname[1] for second
aname[2] and so on, but i didnt do it-->

The variable hold a node set. The xsl:value-of statement selects the
string value, which is the text of the first node in the node set.
If you want to process all nodes, use xsl:apply-templates or
xsl:for-each, for example
  <xsl:for-each select="$aname">
    <xsl:value-of select="."/>
  </xsl:for-each>
