(1)
<xsl:variable name="someName" select="concat(substring('true', 1, 4 - 4 *
(not($tmp))), $tmp)"/>
Or (I prefer this):
(2)
string($default[not($tmp)] | $tmp)
$default is a node-set defined in the stylesheet such that its string value
is "true" , e.g.:
<myDefault:myDefault>true</myDefault:myDefault>
<xsl:variable name="default" select="document('')/*/myDefault:*[1]"/>
(3)
An elegant way is what David Carlisle demonstrated with creating multiple
attributes with the same name.

But that seems pretty verbose. And it will be worse as I have multiple
settings variables with various names.
Is there a more elegant way?
Wow, Lars, if you consider that verbose I must be doing something
terribly wrong...
Assuming, all your global settings follow the same basic XPath
structure, I'd do it as follows:
<xsl:variable name="number-rows">
<xsl:call-template name="get_global_setting">
<xsl:with-param name="setting" select="'number-rows'"/>
</xsl:call-template>
</xsl:variable>
and then provide the appropriate get_global_setting named template. If
your XPath structure doesn't allow for the simple syntax above, you can
always change the "setting" parameter to a "path" parameter.
In an actual XSLT file, I would write the entire variable declaration
above on a single line to get most of the verbosity out of my face. As
an added benefit, if the retrieval method for your global settings
changes, you only have a single place to change your XSLT.
