These are reports of errors in your stylesheet. You are currently
creating an attribute and adding it to an element after you've already
added children to that element, and that's not allowed in XSLT. The
cause is the <xsl:apply-templates> instruction that applies templates
to all the children of the element, when some of the children might
cause the generation of attributes and others the copying of elements.

Try the following stylesheet, which should fix the problem:

<xsl:stylesheet version="1.0"
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
   xmlns:my="my:my"
   exclude-result-prefixes="my"
   >

   <xsl:output omit-xml-declaration="yes" indent="yes"/>
   <xsl:strip-space elements="*"/>

   <my:elNames>
      <name>id</name>
   </my:elNames>

   <xsl:variable name="elNames"
      select="document('')/*/my:elNames/name"/>

   <xsl:template match="@* | node()">
      <xsl:copy>
         <xsl:apply-templates select="@* | node()"/>
      </xsl:copy>
   </xsl:template>

   <xsl:template match="*">
      <xsl:choose>
         <xsl:when test="not(name() = $elNames)">
            <xsl:copy>
               <xsl:copy-of select="@*"/>
               <xsl:apply-templates select="*[name() = $elNames]"/>
               <xsl:apply-templates
                 select="node()[not(name() = $elNames)]"/>
            </xsl:copy>
         </xsl:when>
         <xsl:otherwise>
            <xsl:attribute name="{name()}">
               <xsl:value-of select="."/>
            </xsl:attribute>
         </xsl:otherwise>
      </xsl:choose>
   </xsl:template>

   <xsl:template match="value">
      <xsl:value-of select="."/>
   </xsl:template>
</xsl:stylesheet>

Cheers,
