Default keyword for attribute is att.
att [other attributes] @name = {template}
xsl:attribute is slightly different from
the syntax for xsl:variable,
xsl:param, and xsl:with-param.
The reason for this is that xsl:attribute does not have a select
attribute.
att message={Hello world}
att count1={3}
att count2={val(count(rabbit))}
