There are two ways to do what you want to do, one of which is a shortening
of the other.  The essential thing you have to realise is that you're
constructing an element tree, not putting together strings to give an HTML
file.  To rephrase your question with this in mind: what you want to do is
create an 'INPUT' element whose 'NAME' attribute is equal to the value of
the 'name' attribute of the current node (the 'data' element).

The first way, which is longer but a bit more flexible, is to use
xsl:attribute, which lets you specify the value of an attribute on a result
element in any way you want within its content:

<xsl:for-each select="data">
      <xsl:attribute name="NAME">
        <xsl:value-of select="@name" />
      <xsl:value-of select="@label" />

The second way, which is shorter, but less flexible, is to use an
'attribute-value-template'.  Basically, if you place an XPath (like @name)
within {}s in an attribute value, then the XPath is evaluated to give the
value for the attribute:

<xsl:for-each select="data">
    <INPUT TYPE="CHECKBOX" NAME="{@name}">
      <xsl:value-of select="@label" />

I hope that helps,
