The spec can be found at http://www.w3.org/TR/xslt.

According to section 7.6.2, "Curly braces are not recognized in an attribute
value in an XSLT stylesheet unless the attribute is specifically stated to be
one that is interpreted as an attribute value template; in an element syntax
summary, the value of such attributes is surrounded by curly braces."

In section 5.4, the element syntax summary of xsl:apply-templates is given as
follows:

<xsl:apply-templates
  select = node-set-expression
  mode = qname>

No curly braces around qname after mode, so no, you can't do that.
