"Mounting" means adding a completely "independent" application in a specific path, that then takes care of handling everything under that path, with the _path operations_ declared in that sub-application.

### Top-level application { #top-level-application }

First, create the main, top-level, **FastAPI** application, and its *path operations*:

{* ../../docs_src/sub_applications/tutorial001_py39.py hl[3, 6:8] *}

///

## Declare model attributes { #declare-model-attributes }

You can then use `Field` with model attributes:

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[11:14] *}

`Field` works the same way as `Query`, `Path` and `Body`, it has all the same parameters, etc.

        return new XmlWriterRequestBuilder<>();

    class XmlWriterRequestBuilder<T> {
        Path path;
        OutputStream outputStream;
        Writer writer;
        T content;
        Function<Object, String> inputLocationFormatter;

        public XmlWriterRequestBuilder<T> path(Path path) {
            this.path = path;
            return this;
        }

                  <project path="$PROJECT_DIR$/build-logic/cleanup" />
                  <project path="$PROJECT_DIR$/build-logic/dependency-modules" />
                  <project path="$PROJECT_DIR$/build-logic/documentation" />
                  <project path="$PROJECT_DIR$/build-logic/idea" />
                  <project path="$PROJECT_DIR$/build-logic/integration-testing" />

## Multiple path and query parameters { #multiple-path-and-query-parameters }

You can declare multiple path parameters and query parameters at the same time, **FastAPI** knows which is which.

And you don't have to declare them in any specific order.

They will be detected by name:
