The default locale is set on the Content Platform Engine server. If you do not want to use the default locale, you can pass locale-specific information in the SOAP header. This locale information is passed to the Process Java™ API, which performs any translation-related operations.
For more information, see Localization.
The Process Engine Web Service SOAP header uses the following format for localization:
<xsd:element name="Localization">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="Locale" type="xsd:string"/>
<xsd:element name="Timezone" type="xsd:string" minOccurs="0"/>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
