ipptool: Test will fail when EXPECT directive is seeking a value for a 1setOf that isn't the first in the set

[michaelrsweet]

From @wifiprintguy in ippsample issue 253:

A Get-Printer-Attributes test that examines the contents of an attribute that is of type 1setOf collection will fail if the first instance of that collection doesn't contain a matching member value. For instance, an ippserver configuration (.conf) file that contains this:

ATTR collection     finishings-col-database
{
 MEMBER keyword finishing-template                 'bale'
 MEMBER rangeOfInteger media-sheets-supported      1-150
 MEMBER collection baling
{
   MEMBER keyword baling-type                      'band'
   MEMBER keyword baling-when                      'after-sets'
 }
},
{
  MEMBER keyword finishing-template                 'bind'
  MEMBER rangeOfInteger media-sheets-supported      1-150
  MEMBER collection binding
  {
    MEMBER keyword binding-type                     'spiral'
    MEMBER keyword binding-reference-edge           'left'
  }
}

A .test file with this will fail to find 'bind', but will find 'bind' if the collections are reordered so that 'bale' is second and 'bind' is first:

#####################################
# BALING
#####################################
{
    SKIP-IF-NOT-DEFINED HAVE_BALING

    NAME '[BALING-1] Check finishings-col members support for baling'

    OPERATION Get-Printer-Attributes

    GROUP operation-attributes-tag
        ATTR charset attributes-charset utf-8
        ATTR language attributes-natural-language en
        ATTR uri printer-uri $uri
        ATTR keyword requested-attributes 'finishings-col-database'

    STATUS successful-ok

    EXPECT finishings-col-database/finishing-template OF-TYPE keyword WITH-VALUE 'bale'
}

{
    SKIP-IF-NOT-DEFINED HAVE_BINDING

    NAME '[BINDING-1] Check finishings-col members support for binding'

    OPERATION Get-Printer-Attributes

    GROUP operation-attributes-tag
        ATTR charset attributes-charset utf-8
        ATTR language attributes-natural-language en
        ATTR uri printer-uri $uri
        ATTR keyword requested-attributes 'finishings-col-database'

    STATUS successful-ok

    EXPECT finishings-col-database/finishing-template OF-TYPE keyword WITH-VALUE 'bind'
}

My only conclusion is that ipptool isn't doing a full traversal / search of all collections in the 1setOf, but is instead looking at only the first collection. Please fix this as it is preventing my Finishings 3.0 prototyping work to proceed.
