Problem loading a local layout file in LyX 2.5.1

[ehud.each785 at passmail.com]

I am trying to create a local layout file named `test.layout` to be used with a LyX 2.5.1 document.

My test.layout file is attached to the message. 

The lyx document and test.layout are saved in the same directory on the hard disk.

I want the layout file to use the `book` document class.

When I created a new lyx file, I browsed for the `test.layout` file after clicking on "Local Class..." in the document settings menu.

I then have made some changes to the layout file with a text editor and tested for the changes in LyX by using the function layout-reload.

Then LyX reports:

Due to some error in it, the layout file: test could not be loaded. A default textclass with default layouts will be used. LyX will not be able to produce correct output.

Un-doing the changes in the text editor and hitting layout-reload function in lyx result in the same message.

I would really like to understand what is wrong with my layout file.
