Attribute source ranges are not normalized correctly #2067
Description
As reported in #1933:
Here's my PR on the Rascal project. It works! But... I have a missing Range on the attributes on the top node.
For testing purposes I was parsing the pom.xml file of the rascal project itself:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>org.rascalmpl</groupId>
<artifactId>rascal</artifactId>
<version>0.35.0-RC2-SNAPSHOT</version>
<packaging>jar</packaging>
... SNIP!
The project node has an xsi:schemaLocation attribute.
Here's some output of the readXML function that will print the filename only if the attribute sources ranges are -1:
rascal>import IO;
ok
rascal>import lang::xml::IO;
ok
rascal>iprintln(readXML(|cwd:///pom.xml|, trackOrigins=true), lineLimit=-1)

schemalocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"),
src=|cwd:///pom.xml|)
Here we see the srcs map saying: ("schemalocation":|cwd:///pom.xml|), which is caused by the AttributeRange.valueRange() having a begin offset of -1. I tracked this with the Java debugger. Is this supposed to happen? Or is the top-node somehow different?
