I think you just want

<xsl:template match="xxx">
<xxx attr="default">
<xsl:copy-of select="@*"/>

  ..
</xxx>
</xsl:template>

which will mean that xxx has the attributes from the source, plus
possibly attr="default" if teh source did not have that attribute.

Note I'm not sure if that's quite what you want as your two code
examples used different tests 
one had not(@attr) 
and the other had "@attr != ''
attr=""
would be false for both of those. Which you want depends on whether
you want an empty attribute (as well as a missing attribute) to be
replaced by <xxx attr="default">.
