This much is kosher.

This, however, doesn't work as expected because the value of the match 
attribute should [usually] be the name of the matched element or attribute, 
not their values.  Thus, it would something like:

match="@name"

or

match="@name[. = 'quicksearch']"

The "usually" above is because it's possible to match using non 
name-specific expressions: node() to match any node, text() for text nodes, 
@* for attributes, etc.

So now we know why the template doesn't fire.  The "value of the attribute" 
is being output because XSLT has default, behind-the-scenes templates that 
automatically output certain nodes, if not overridden.  Thus, if you left 
things as they were, then add the following template, you wouldn't get even 
the attribute value output:

<xsl:template match="@*"/>
