when declaring a custom embed attribute of type selection, the declared values do not work:

• value is not stored
• if editor is disabled, the custom attribute is not present in the <embed> tag

test:

set in content.ini:

[embed-type_images]
CustomAttributes[]=dropbox

in ezoe_attributes.ini

[CustomAttribute_dropbox]
Name=Dropbox
Type=select
Default=1
Selection[]
Selection[0]=one
Selection[1]=two
Selection[2]=three

• add an image to a xml block
• select any value from the "dropbox" attribute, publish
• edit again previous image. the selected value in "dropbox" was not saved
• confirm by disabling the editor: the dropbox attribute is not present in the tag
