Compilation error: help: message: not implemented

[atcol]

I want to use xml-schema with http://schemas.opengis.net/wms/1.3.0/capabilities_1_3_0.xsd and I tried with this example:

#[macro_use]
extern crate yaserde_derive;

use log::debug;
use std::io::prelude::*;
use xml_schema_derive::XmlSchema;
use yaserde::{YaDeserialize, YaSerialize};

#[derive(Debug, XmlSchema)]
#[xml_schema(source = "schemas/wms/capabilities_1_3_0.xsd", target_prefix = "wms")]
struct Wms;

fn main() {
    println!("Hello, world!");
}

but I get the following error:

error: proc-macro derive panicked
 --> src/main.rs:9:17
  |
9 | #[derive(Debug, XmlSchema)]
  |                 ^^^^^^^^^
  |
  = help: message: not implemented

My Cargo.toml has:

[dependencies]
yaserde_derive = "0.4.1"
yaserde = "0.4.1"
xml-schema-derive = "0.0.3"
xml-schema = "0.0.3"
xml-rs = "0.8.3"
log = "0.4.8"

Hello !

XML-schema still very young and not support all XSD for now.
I have to take a look on your XSD to see what is missing to support them.
