Will future versions of Tamino support the attribute “nillable” for elements?

Thanks

Hi

so far, support for nillable is not on our “high priority” list for the next version.
In general, however, we intend to complete the XML schema support step by step.

OK. Let’s say I have defined a schema in which there is an element e with type xs:date. Without specifying nillable, a document with element e having an empty content will be invalid. is there a way to design a schema, without using nillable, such that element e can accept value that is either a valid date, or empty? Thanks

Hi

just model the element as optional, i.e.

<xs:element name=“theDateElement” type=“xs:date” minOccurs=“0”/>

I think, this allows the element to be missing or present with a data value, but not to be empty. A solution with XML schema means would be the usage of union tpyes, but these are not supported by Tamino. You can, however, define a default value. Then, an empty element is accepted on insert. On retrieval, it will contain the default value.

Hi,

How should I do if I need a date type element, with an attribute. I have a value for the attribute, but not for the element:

In such a case the optional element does not work because the element exist. I have the a schema validation error.
Thanks

Hi JP

the schema for an empty element with an attribute would look e.g. as follows:

<xs:element name=“theDateElement”>
xs:complexType
<xs:attribute name=“myAtt”/>
</xs:complexType>
</xs:element>

But this does not include the date type in the element does it ? I need to be able to put a date in the element with the attribute, or an empty element with the attribute.
I such a case I would need the nillable element . How can I do with tamino ?

The following should work with Tamino 4.4

<xs:element name=“theDateElement” nillable=“true”>
xs:complexType
xs:simpleContent
<xs:extension base=“xs:date”/>
</xs:simpleContent>
<xs:attribute name=“myAtt”/>
</xs:complexType>
</xs:element>
