       RSL Predicates.

       The functions in this group return boolean values indicating whether an RSL syntax tree is of a
       particular type.

intglobus_rsl_is_boolean(globus_rsl_t*ast)
       RSL boolean test. The globus_rsl_is_boolean() function tests whether the the RSL pointed to by the ast
       parameter is a boolean composition of other RSL parse trees. The syntactically understood boolean
       compositions are '&' (conjunction), '|' (disjunction), and '+' (multi-request). Some bexamples of RSL
       booleans are

       & ( "queue" = "debug") ( "max_time" = "10000")
       | ("count" = "1")("count" = "10")
       + ( &("executable" = "1.exe") ) ( & ("executable" = "2.exe" )

       Parametersast Pointer to an RSL parse tree structure.

       Returns
           The globus_rsl_is_boolean() function returns GLOBUS_TRUE if the RSL parse tree pointed to by ast is a
           boolean composition; otherwise, it returns GLOBUS_FALSE.

   intglobus_rsl_is_boolean_and(globus_rsl_t*ast)
       RSL boolean and test. The globus_rsl_is_boolean_and() function tests whether the the RSL pointed to by
       the ast parameter is a boolean 'and' composition of RSL trees.

       An example of a boolean and relation is

       & ( "queue" = "debug" ) ( "executable" = "a.out" )

       Parametersast Pointer to an RSL parse tree structure.

       Returns
           The globus_rsl_is_boolean_and() function returns GLOBUS_TRUE if the RSL parse tree pointed to by ast
           is a boolean and of RSL parse trees; otherwise, it returns GLOBUS_FALSE.

   intglobus_rsl_is_boolean_multi(globus_rsl_t*ast)
       RSL boolean multi test. The globus_rsl_is_boolean_multi() function tests whether the the RSL pointed to
       by the ast parameter is a boolean 'multi-request' composition of RSL trees.

       An example of a boolean multie-request relation is

       + ( &( "executable" = "exe.1") ( "count" = "2" ) )
         ( &( "executable" =" exe.2") ( "count" = "2" ) )

       Parametersast Pointer to an RSL parse tree structure.

       Returns
           The globus_rsl_is_boolean_multi() function returns GLOBUS_TRUE if the RSL parse tree pointed to by
           ast is a boolean multi-request of RSL parse trees; otherwise, it returns GLOBUS_FALSE.

   intglobus_rsl_is_boolean_or(globus_rsl_t*ast)
       RSL boolean or test. The globus_rsl_is_boolean_or() function tests whether the the RSL pointed to by the
       ast parameter is a boolean 'or' composition of RSL trees.

       An example of a boolean or relation is

       | ( "count" = "2" ) ( "count" = "4" )

       Parametersast Pointer to an RSL parse tree structure.

       Returns
           The globus_rsl_is_boolean_or() function returns GLOBUS_TRUE if the RSL parse tree pointed to by ast
           is a boolean and of RSL parse trees; otherwise, it returns GLOBUS_FALSE.

   intglobus_rsl_is_relation(globus_rsl_t*ast)
       RSL relation test. The globus_rsl_is_relation() function tests whether the the RSL pointed to by the ast
       parameter is a relation. The RSL syntax supports the following relation operations:

       =   Equal

       !=  Not Equal

       >   Greater Than

       >=  Greater Than or Equal

       <   Less Than

       <=  Less Than or Equal

       <=  Less Than or Equal

       Some examples of RSL relations are

       "queue" = "debug"
       "queue" != "slow"
       "min_memory" > "1000"
       "max_wall_time" >= "60"
       "count < "10"
       "host_count" <= "5"

       Note
           GRAM only supports equality relations.

       Parametersast Pointer to an RSL parse tree structure.

       Returns
           The  globus_rsl_is_relation() function returns GLOBUS_TRUE if the RSL parse tree pointed to by ast is
           a relation; otherwise, it returns GLOBUS_FALSE.

   intglobus_rsl_is_relation_attribute_equal(globus_rsl_t*ast,char*attribute)
       RSL attribute name test. The globus_rsl_is_relation_attribute_equal() function tests whether the the  RSL
       pointed to by the ast parameter is a relation with the attribute name which matches the string pointed to
       by the attribute parameter. This attribute name comparison is case-insensitive.

       Parametersast Pointer to an RSL parse tree structure.

       Returns
           The  globus_rsl_is_relation_attribute_equal()  function  returns  GLOBUS_TRUE  if  the RSL parse tree
           pointed to by ast is a relation and its attribute name matches the attribute parameter; otherwise, it
           returns GLOBUS_FALSE.

   intglobus_rsl_is_relation_eq(globus_rsl_t*ast)
       RSL equality operation test. The globus_rsl_is_relation_eq() function tests whether the the  RSL  pointed
       to by the ast parameter is an equality relation. An example of an equality relation is

       "count" = "10"

       Parametersast Pointer to an RSL parse tree structure.

       Returns
           The  globus_rsl_is_relation_lessthan()  function returns GLOBUS_TRUE if the RSL parse tree pointed to
