xslt concat variable and string

I'm looking for a simpler way to concatenate a variable and a string value. Currently I have the following:

<xsl:for-each select="$var_asset_name">
    <xsl:attribute name="Asset_Name" select="fn:concat(fn:string(.), '_title')"/>
</xsl:for-each>

with $var_asset_name defined further up. This works, but I'm wondering if there is a simpler way to achieve the same result. I have tried 

<xsl:attribute name="Asset_Name" select="fn:concat($var_asset_name, '_title')"/>

but it did not work (Error: The supplied sequence ('2' item(s)) has the wrong occurrence to match the sequence type xs:anyAtomicType ('zero or one'))

Thanks in advance.

At the moment, all XPath versions have a string concatenation function, not a string concatenation operator: XPath 1.0, XPath 2.0, XPath 3.1

With this input:

<root/>

The following XSLT(which uses attribute value template):

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:variable name="var_asset_name">stack</xsl:variable>
<xsl:template match="root">
    <root Asset_Name="{$var_asset_name}_overflow"/>
</xsl:template>
</xsl:stylesheet>

Would produce:

<?xml version="1.0" encoding="utf-8"?>
<root Asset_Name="stack_overflow"/>

I hope you wanted an easier way to create attributes.
