About Layer Names
Layers are identified by their names. Layer names can include numeric and alphanumeric characters and a maximum of 31 characters.
* Do not begin a layer name with a hyphen “-“.
Layers displayed on the Layer Tree are first sorted by their numeric names followed by the alpha numeric layer names. Layer names that include the alphanumeric characters are sorted alphabetically.
