Is it possible to remove whitespace when inserting values without
using xsl:value-of?

This is my template. It outputs HTML meta tags, but I can't figure out
how to normalize the space when not using xsl:value-of. I'm using xslt
1.0.

<xsl:template name="metadata">
<meta http-equiv="Content-Type" name="dc.title"
content="{eadheader/filedesc/titlestmt/titleproper}"/>

<meta http-equiv="Content-Type" name="dc.title"
content="{normalize-space(eadheader/filedesc/titlestmt/titleproper)}"/>
