Output (for diagnostics) a representation of the type of an item. This does not have to be the most specific type

Get the SimpleType object for a built-in simple type code

Returns: the SimpleType, or null if not found

Get a type that is a common supertype of two given types

Parameters: t1 the first item type t2 the second item type th

Returns: the item type that is a supertype of both the supplied item types

Get the ItemType of an Item

Determine whether two primitive atomic types are comparable

Parameters: t1 the first type to compared. This must be a primitive atomic type as defined by ItemType t2 the second type to compared. This must be a primitive atomic type as defined by ItemType ordered true if testing for an ordering comparison (lt, gt, le, ge). False if testing for an equality comparison (eq, ne)

Returns: true if the types are comparable, as defined by the rules of the "eq" operator

Test whether a given type is (some subtype of) node()

Parameters: type The type to be tested

Returns: true if the item type is node() or a subtype of node()

Test whether the supplied type, which must be a primitive type, is one of the numeric primitive types

Parameters: t the type being tested

Returns: true if the type is integer, double, float, decimal, or the abstract type "numeric"

Determine whether a primitive type is ordered. Note that the rules for this differ between XPath and XML Schema: these are the XPath rules.

Parameters: type the primitive item type being tested

Returns: true if the types are potentially comparable. For abstract types (type=ATOMIC) we give the benefit of the doubt and return true.

Determine whether this type is a primitive type. The primitive types are the 19 primitive types of XML Schema, plus xs:integer, xdt:dayTimeDuration and xdt:yearMonthDuration; xdt:untypedAtomic; the 7 node kinds; and all supertypes of these (item(), node(), xdt:anyAtomicType, xdt:number, ...)

Parameters: code the item type code to be tested

Returns: true if the type is considered primitive under the above rules

Get the relationship of two schema types to each other
