Use

  <xsl:when test="normalize-space(@availableInventory)">

The normalize-space function will produce a string with leading and trailing
whitespace removed, and adjacent embedded whitespace collapsed to a single
space. A string will test false if it is completely empty (zero length).

You could also use string(@availableInventory) if you don't need to strip
whitespace.

You probably noticed that test="@availableInventory" was always true when
there was an availableInventory attribute; this is testing a node-set to see
if it has any nodes in it.
