.aero registration fails with an "XML parser" error

Symptoms

When you register a .aero domain, the order fails with an error like this:

Incorrect contact's details: XX000000-XX, E00000, Errors occurred during processing., Parser error., XML parser = The content of elements must consist of well-formed character data or markup.

This happens even though the .aero ID and password (key) were issued by the registry and are correct.

Cause

.aero requires proof of aviation relationship. You enter it in the contact as:

If the key contains the symbols <, > or &, our system cannot read it correctly and the order is rejected. Other symbols (quotes, backslash, brackets and so on) are not a problem.

Solution

In the .aero Password field, replace those three symbols like this:

If the key has Type this instead
& &amp;
< &lt;
> &gt;

Leave every other character as it is.

Example

Save the contact and register the domain again.
