What exactly does this WSO2 ESB echo endpoint?

Question

I am very new in WSO2 and I have the following doubt related to an ESB project on which I am working.

In this ESB application I am sending a message to a named endopoint mediator, something like this:

<send>
    <endpoint key="echoEndpoint"/>
</send>

This is the contend of the related echoEndpoint.xml file in my project:

<?xml version="1.0" encoding="UTF-8"?>
<endpoint name="echoEndpoint" xmlns="http://ws.apache.org/ns/synapse">
    <address format="soap11" statistics="enable" trace="enable" uri="http://localhost:8280/services/echo"/>
</endpoint>

So what exactly does this endpoint? The http://localhost:8280/services/echo is something like a predefined endopoined provided natively by WSO2? or what?

echo service included into esb/ei by default. You can see it in Carbon Panel -> Main -> Manage -> Services. There you can test it via "Try It" feature. It has few methods:

echoInt extected to get integer as argument and returned same integer value
echoString - expected to get string value as argument and returned same value
echoOMElement - received XML as argument and returned same XML

and some other methods. General idea - this service returned same value as it is received.

This service is helpful for testing purposes.
