Standard support
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.
JSON support
See JSON support.
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.
1
<xf:submission id="my-submission"
2
    method="post"
3
    nonrelevant="empty"
4
    resource="http://example.org/rest/draft/"
5
    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:
1
<xf:submission id="my-submission"
2
    method="post"
3
    validate="false"
4
    relevant="false"
5
    resource="http://example.org/rest/draft/"
6
    replace="none"/>
Copied!
XForms 2.0 introduces nonrelevant (while keeping relevant for backward compatibility) for clarity:
1
<xf:submission id="my-submission"
2
    method="post"
3
    validate="false"
4
    nonrelevant="keep"
5
    resource="http://example.org/rest/draft/"
6
    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:
1
<xf:submission id="my-submission"
2
    method="get"
3
    serialization="none"
4
    resource="http://example.org/document.xml"
5
    replace="instance"
6
    instance="my-instance"/>
