It's not that the submission *puts* those namespaces when serializing,
that the data model *already contains* those namespaces in scope and
therefore they get serialized.

It seems wrong to me to handle this at submission time if the problem
to be solved is to fixup undesired namespaces due to the inlining of
the data model definition within <xf:instance>.

Instead, I think it should be done at the time the data model is created.

Also note that this problem does not exist if the instance is external, as in:

  <xf:instance src="my-instance.xml"/>

In our implementation we support `xxf:exclude-result-prefixes` (based
on XSLT's `exclude-result-prefixes` attribute - reusing that name
might not have been a great choice). You place that attribute on
<xf:instance>:

    <xf:instance id="fr-service-request-instance"
xxf:exclude-result-prefixes="#all">
      <request>...</request>
    </xf:instance>

This also puts the attribute which control the data model closer from
the data itself, like when one uses xmlns="":

    <xf:instance id="fr-service-request-instance" xmlns="">
      <request>...</request>
    </xf:instance>

or:

    <xf:instance id="fr-service-request-instance">
      <request xmlns="">...</request>
    </xf:instance>

We could support two attributes on <xf:instance>:

- `includenamespaceprefixes`
- `excludenamespaceprefixes`

These two attributes can also be supported on <xf:submission> and
operate at the time of serialization, if need be. But if the data
model is clean, the need for the attributes at submission time is
smaller.

You would need to remember to use the `excludenamespaceprefixes`
attribute as needed when declaring inline instances:

    <xf:instance id="fr-service-request-instance"
excludenamespaceprefixes ="#all">
      <request>...</request>
    </xf:instance>
