Re: newbie question on p:validate-with-xml-schema

Hi David

The XML declaration is purely a serialization feature. Along with other
serialization options, it can be controlled using the serialization
attributes which can be attached to various XProc elements.

If the XML document in question is the output of your entire pipeline, you
should be able to use the p:serialization element to specify how you want
your pipeline's result port to serialize:

<p:serialization port="result" omit-xml-declaration="false"/>

http://www.w3.org/TR/xproc/#p.serialization

Similarly, if your pipeline is itself responsible for storing the XML, e.g.
using p:store, you can control its serialization directly:

<p:store href="my-result.xml" omit-xml-declaration="false"/>
