Description

In our project we are using SAX2 parsing. We recently upgraded to Xerces-C 3.2.0 and now we get misleading error messages when the schema is unknown. A file with the following content

<routes xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://sumo.dlr.de/xsd/blub_file.xsd"/>

used to generate the message

Error: unable to open file 'http://sumo.dlr.de/xsd/blub_file.xsd'
In file 'input_routes.rou.xml'
At line/column 1/0.

Now it says:
Error: whitespace expected
In file 'input_routes.rou.xml'
At line/column 2/50.

The strange thing is that it fails only on Linux (ubuntu 16.04) and it used to work with version 3.1.3

I did the build for Xerces-C 3.2.0 manually using the standard configure, make, sudo make install process
