Steve Lawrence commented on DAFFODIL-2953:
------------------------------------------
It would be nice if we could implement a Locator for our loader, I imagine
Xerces must somehow keep track of line/column information.
As a temporary fix, we should at least change it so if there is no line/col
information then we should not output it. The above example would just output
{quote}
Schema context: Location src/main.dfdl.xsd
{quote}
Note that going back to Daffodil 3.3.0, we output aa similar error as now, but
there is also a SDW that includes line/column information. Things have changed
a lot since then, but at one point this information was kindof available.

> Project: Daffodil
> Issue Type: Bug
> Components: Front End
> Reporter: Steve Lawrence
> Priority: Major
>
> If I have something like this in a schema:
> {code:xml}
> <xs:import ... schemaLocation="/does/not/exists.dfdl.xsd" />
> {code}
> Then I get an error like this:
> {quote}
> [error] Schema Definition Error: Error loading schema due to Unable to
> resolve schemaLocation: /does/not/exists.dfdl.xsd
> Schema context: Location line -1 column -1 in src/main.dfdl.xsd
> {quote}
> Looks like this error message is from Xerces.
