routeIdType doesn't allow numbers

[mzeis]

When defining a route in etc/frontend/routes.xml:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../../../../lib/internal/Magento/Framework/App/etc/routes.xsd">
    <router id="standard">
        <route id="mzeis_test123" frontName="test123">
            <module name="Mzeis_Test123" />
        </route>
    </router>
</config>

The XSD doesn't allow to use numbers in the id attribute of the route node, see routes.xsd and routes_merged.xsd.

Is there a reason for doing that? Given that numbers are valid in the module names as well as routerIdType and I expect developers to use the name of the module for the route id in many cases I'd suggest to allow numbers (or better: the same pattern as for the module name).

Thanks for reporting the issue @mzeis.
Yes, it makes sense to allow numbers for route id attribute. I have created an issue to track this : MAGETWO-37855

👍 We need numbers to. Our prefix starts with "n98".

Didn't test but the code change looks good, thanks.
