Reading the specs raw from Github

Hello XProc people,

Probably I am not the only one who can tell from "side effects" when the
committee has been busy at work updating and improving things.

For example, recently a pipeline of mine broke ... apparently because
relevant pieces of the specs in the 3.0-steps repository now use XInclude.

No problem, XProc can do XInclude. But I tried, and this does not work:

<p:declare-step xmlns:p="http://www.w3.org/ns/xproc" version="3.0">

    <p:output/>

    <p:load href="
https://raw.githubusercontent.com/xproc/3.0-steps/master/step-text/src/main/xml/specification.xml
"
      content-type="application/xml"/>

    <p:xinclude/>

</p:declare-step>

This returns an error in both XML Calabash and Morgana IIIse.

It returns a different error related to the same cause if you leave
'content-type="application/xml"' from the p:load. (I blame Github.)

What is up with this? Is there any way to read the raw XML off Github, as
XML?

If not, are there alternative pathways -- short of cloning the repository
and reading via file: not http: ? i.e. alternative all-XProc approaches to
reading the specs dynamically in place.

Thanks for any insights,
Wendell
