Introduction

Orbeon Forms supports most standard XForms features, including:

• the specified processing processing model

• events: xforms-submit, xforms-submit-serialize, xforms-submit-done, and xforms-submit-error

• all HTTP and HTTPS methods

• serializations: application/x-www-form-urlencoded, application/xml, application/json (SINCE Orbeon Forms 2016.1), multipart/form-data, as well as extensions.

• replacements: all, instance, and text

• SOAP support

One exception is the lack of support for multipart/related.

For more information, please visit the XForms 1.1 specification.

Controlling non-relevant nodes

[SINCE Orbeon Forms 2017.1]

The XForms 2.0 nonrelevant attribute takes values

• keep: all values are serialized,

• remove: non-relevant values are not serialised

• empty: non-relevant nodes are serialized as empty values

The default is remove.

<xf:submission id="my-submission"
    method="post"
    nonrelevant="empty"
    resource="http://example.org/rest/draft/"
    replace="none"/>

Disabling validation and relevance handling

Orbeon Forms supports the XForms 1.1 validate and relevant attributes on <xf:submission>.

NOTE: The relevant attribute is deprecated in favor of the XForms 2.0 nonrelevant attribute.

These boolean attributes disable processing of validation and relevance pruning respectively for a given submission:

<xf:submission id="my-submission"
    method="post"
    validate="false"
    relevant="false"
    resource="http://example.org/rest/draft/"
    replace="none"/>

XForms 2.0 introduces nonrelevant (while keeping relevant for backward compatibility) for clarity:

<xf:submission id="my-submission"
    method="post"
    validate="false"
    nonrelevant="keep"
    resource="http://example.org/rest/draft/"
    replace="none"/>

Controlling serialization

Orbeon Forms supports the XForms 1.1 serialization on <xf:submission>. This is particularly useful to specify the value none with a get method:

<xf:submission id="my-submission"
    method="get"
    serialization="none"
    resource="http://example.org/document.xml"
    replace="instance"
    instance="my-instance"/>
