<xsl:template match="@*|node()">
<xsl:copy>
<xsl:namespace name="epub">http://www.idpf.org/2007/ops</xsl:namespace>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>

(Note: untested. In particular I haven't checked what will happen to
comments and processing instructions are matched with this template --
instead, trusting the language designers to have specified the right
thing, i.e. that the xsl:namespace instruction is then ignored.)

<xsl:template match="/*">
<xsl:copy>
<xsl:namespace name="epub">http://www.idpf.org/2007/ops</xsl:namespace>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>

The namespace will then be bound to every node in your result.
Consequently you will see it declared on the document element in your
output -- and probably nowhere else. (I say 'probably' because that is
the way a well-designed serializer will do it, other things being
equal.)

Cheers,
