SOAP Attributes

SOAP elements can have the attributes: actor, encodingStyle and mustUnderstand.

The Actor Attribute

The Actor attribute defines the URI for which the header elements are intended.

The Actor attribute has the following syntax:

soap:actor="URI"

Example:

<soap:Header>
  <m:local xmlns:m="http://www.w3schools.com/local/"
   soap:actor="http://www.w3schools.com/appml">
    <m:language>en</m:language>
    <m:currency>USD</m:currency>
  </m:local>
</soap:Header>

The encodingStyle Attribute

The encodingStyle element is used to define the format (data types) that is used in the document.

The encodingStyle attribute has the following syntax:

soap:encodingStyle="URI"

Example:

<soap:Envelope
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
...
Message information goes here
...
</soap:Envelope>

The mustUnderstand Attribute

The mustUnderstand attribute is used to define if the receiver of a message must process a header element.

The mustUnderstand attribute has the following syntax:

soap:mustUnderstand="boolean"

Example:

<soap:Header>
  <m:local xmlns:m="http://www.w3schools.com/local/">
    <m:language soap:mustUnderstand="0">en</m:language>
    <m:currency soap:mustUnderstand="1">USD</m:currency>
  </m:local>
</soap:Header>
