XML\RNG Validation Wierdness

[feamsr00]

Describe the bug
When validating the build.xml file with the relaxng schema it insists that "selector" is missing in the <project> root tag and all <target> tags.

Steps To Reproduce
Add the rng file as a schema definition to the top of the file.

<?xml version="1.0" encoding="UTF-8"?>
<?xml-model href="https://raw.github.com/phingofficial/phing/3.0.0-RC3/etc/phing-grammar.rng"
            type="application/xml"
            schematypens="http://relaxng.org/ns/structure/1.0" ?>

Expected behavior
Smooth error correction and autocomplete bliss.

Screenshots / terminal output
"selector" element demands:

element "target" incomplete; missing required element "selector"

Additionally complains about passthrough attribute. Surely this should be a boolean OR a string, yes?

value of attribute "passthru" is invalid; must be a boolean

Additional context
I think this is caused by these lines in the phing-grammar.rng file.

    <define name="project">
        <element name="project">

                <ref name="optionaltasks"/>
#L321           <ref name="selector"/>
            </interleave>
        </element>
    </define>

Maybe those selectors are supposed to be wrapped in the optional tags?

Hi @feamsr00. You could be very right. IntelliJ's RNG support is not great, so it's very possible things are less than optimal. What editor are you using?

passthru is supposed to be a boolean, looks like your editor is tripping over the variable expansion (${build.isVerbose}).

I'm using VS Codium (VS Code clode) 1.74.2 with Redhat's XML extension

Heh. I will grant that property file variable expansion might be a lot to ask from xml editing. Moreover, asking every attribute to allow a string type as well might also be a bridge too far, yes?
