ST - xsd-type , Validation

Syntax
... xsd-type="type"
[xsd-maxInclusive="max"]
[xsd-maxExclusive ="max"]
[xsd-minInclusive="min"]
[xsd-minExclusive ="min"]
[xsd-totalDigits="dgts"]
[xsd-fractionDigits="dgts"] ...

Effect
These attributes can be used with
tt:value , and tt:write and tt:read to validate the value.
The attribute xsd-type can be used to specify an XML schema data type type . The serialized or deserialized value must be in the value range of this type. If not, an exception of the class CX_ST_VALIDATION_ERROR is raised, which is not caught directly but by using CX_ST_SERIALIZATION_ERROR ,
CX_ST_DESERIALIZATION_ERROR , and its superclasses instead. The following subtypes of xsd:decimal can be specified for type
:
xsd:byte, xsd:decimal, xsd:int, xsd:integer, xsd:long, xsd:negativeInteger, xsd:nonNegativeInteger, xsd:nonPosistiveInteger, xsd:positiveInteger, xsd:short, xsd:unsignedByte, xsd:unsignedInt, xsd:unsignedLong , and xsd:unsignedShort .
Together with the attribute xsd-type , the following "constraining facets" permitted by the XML schema can be specified as further attributes:

xsd-maxInclusive , xsd-maxExclusive

The value must be less than or equal to or less than max . max
must be in the value range of the XML schema data type and cannot be less than a simultaneous lower limit min .

xsd-minInclusive , xsd-minExclusive

The value must be greater than or equal to or greater than min . min must be in the value range of the XML schema data type and cannot be greater than a simultaneous upper limit max .

xsd-totalDigits , fractionDigits

The value can have a maximum of dgts digits or decimal places. dgts must fit the other restrictions.
After the transformation from ABAP, serializations perform the validation to XML . Before the transformation from XML , deserializations perform the validation to ABAP. In both cases, the data type of the bound ABAP data object is ignored.

Example
Serialization of ABAP Data with Validation
<(><<)>tt:transform
xmlns:tt="http://www.sap.com/transformation-templates">
tt:root name="NUM"/
<(><<)>tt:template>
<(><<)>Number>
<(><<)>tt:value ref="NUM"
xsd-type="short" xsd-minInclusive="30000"/
<(><<)>/Number>
<(><<)>/tt:template>
/tt:transform

The transformation only accepts numbers between 30000 and 32767. The following ABAP program calls the transformation and catches the validation exceptions.
PARAMETERS int TYPE i.

DATA xml_string TYPE string.

TRY.
CALL TRANSFORMATION ...
SOURCE num = int
RESULT XML xml_string.
WRITE / 'OK'.
CATCH cx_st_error.
WRITE / 'Not OK'.
ENDTRY.
