That might be fine legally, but it's definitely unacceptable.

Similarly, our nicely structured comments like

<!--
    Test name: csv_test
       Schema: csv.dfdl.xsd
         Root: file
      Purpose: This test is to exercise the csv schema.
  -->

turns into

<!-- Test name: csv_test Schema: csv.dfdl.xsd Root: file Purpose: This test is 
    to exercise the csv schema. -->

But there is a good fix for this, (at least as far as Eclipse tooling is concerned). You can use XML's so called "Processing Instructions" to hold this content. Processing Instructions are part of the XML information model, but almost nothing uses them. (xsl-stylesheets are the only use I know of). They can have anything in them except the sequence '?>' which ends them.

Test name: csv_test
       Schema: csv.dfdl.xsd
         Root: file
      Purpose: This test is to exercise the csv schema.
  -->

turns into

<!-- Test name: csv_test Schema: csv.dfdl.xsd Root: file Purpose: This test is 
    to exercise the csv schema. -->

Tools like Eclipse have a setting to turn this "feature" off. See Eclipse Settings for DFDL Schema Authoring/Editing. Other tools may have similar options.

An alternative is to use XML Processing Instructions instead of comments. For I tested these banners and comments and eclipse will not reformat them when auto-formatting, and they are ignored by the TDML runner and by Daffodil. So, for example, our nicely formatted block comment can be done like so:

...

And then auto-reformatting won't mess it up. Our copyright banner can be similarly bracketed.
