Better mark validation error in topic

[jelovirt]

Which DITA-OT version and how was it run. If I mock a test case like that and run it with 4.2 on the command line, I get

Error: file:/Volumes/tmp/src/topic.dita:3:17: Attribute value "%50" of type ID must be an NCName when namespaces are enabled.

The message content comes from SAXException thrown by the XML parser. In order to get some message ID to the message, we could add a generic parsing message that doens't have a <reason> other than the message text from the XML parser.

So if I run DITA OT 4.2 on Windows on a DITA Map which contains a topic like this:

<?xml version='1.0' encoding='UTF-8'?>

<!DOCTYPE topic PUBLIC "-//OASIS//DTD DITA Topic//EN" "topic.dtd">

<topic id="%50">
    
<title>Introduction</title>

</topic>


the command line I run and the error look like this (notice no [Error:] marker before the reported error):

"C:\Users\radu_coravu\Downloads\dita-ot-4.2/bin/dita.bat" -f html5 -o D:\samples\dita\flowers/out/html5 -t D:\samples\dita\flowers/temp/html5 -i D:\samples\dita\flowers\flowers.ditamap
file:/D:/samples/dita/flowers/topics/introduction.dita:3:17: Attribute value "%50" of type ID must be an NCName when namespaces are enabled.

On Mac OS indeed there is an "Error:" marker with a red foreground when running about the same command.

Ok, so this is a case where on Windows the CLI doesn't use colours in the log and the prefix is missing. I'll open a PR to make sure the prefixes are output on Windows too.

[raducoravu]

@jelovirt yes, also when the -no-colors flag is used the prefix should be output as well.
