XJC binding file: override package based on namespace instead of schemaLocation - jaxb

Question

I'd like to override package for my schema via binding .xjb file.
It is done with:
<schemaBindings>
<package name="com.schema.common" />
</schemaBindings>
JXC compiler expects context for above code, defined via schemaLocation.
I store .xsd and .xjb files in separate directories and this looks ugly (like all Java EE):
<bindings schemaLocation="../../../../wsdl/common_v47_0/CommonReqRsp.xsd">
<schemaBindings>
<package name="com.schema.common" />
</schemaBindings>
</bindings>
Is it possible to define bindings context without relative path in schemaLocation?
I've seen SCD ("schema component designator"). It looks promising but I can't find reference for this syntax...

Here is the magic of SCD:
<?xml version="1.0" encoding="UTF-8"?>
<bindings xmlns="http://java.sun.com/xml/ns/jaxb" version='2.1'
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:tns="http://example/schema/common_v47_0">
<bindings scd="x-schema::tns">
<schemaBindings>
<package name="com.schema.common" />
</schemaBindings>
</bindings>
</bindings>
All parts are important. SCD was introduced in version='2.1'.
I found reference at https://github.com/highsource/maven-jaxb2-plugin/wiki/Configure-Target-Packages-in-Binding-Files
SCD is extension of JAXB standard and implementation can be investigated in JAXB RI source tree:
