Doubling the curly braces fixes the problem.
I think the question also requires an explanation: curly braces in
attributes of literals (and also some xslt instructions) are used to
mark attribute value templates
(http://www.w3.org/TR/xslt#attribute-value-templates). These allows to
put a result of an expression inside a value of an attribute (e.g.
link="xxx{1+1}" would output link="xxx2". In your case, {basedir} is
an attribute value template, expression basedir is evaluated and in
your context, it returns an empty sequence, which is serialized into
an empty string.

Interesting, doubling the curly braces seems to do what you want:
$ echo "<foobar/>" | xsltproc curly.xsl -
<target name="clean"><delete dir="${basedir}/target"/></target>

$ cat curly.xsl
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
<xsl:output omit-xml-declaration="yes" />
<xsl:template match="/">

Subject: [xsl] curly braces in attributes
I am trying to generate xml that contains attributes with with curly
braces.
My style sheet has something like:
<target name="clean" >
<delete dir="${basedir}/target" />
</target>
The results I am getting now is:
<target name="clean" >
<delete dir="$/target"/>
</target>
I am expecting the same to output the same text. I tried to use
<xsl:text> and CDATA. The only way I was able to get the output I
needed is using CDATA inside <xsl:text> for the parts,
I need to output unchanged and unescaped.
Is there a better to disable expression evaluation. Thank you.
