7495 Lists the layers, separated by spaces, recommended for
7496 use with this layer.
7497 Optionally, you can specify a specific layer version for a
7498 recommendation by adding the version to the end of the
7499 layer name.
7500 Here is an example:
7501 <literallayout class='monospaced'>
7502 LAYERRECOMMENDS_mylayer = "anotherlayer (=3)"
7503 </literallayout>
7504 In this previous example, version 3 of "anotherlayer" is
7505 compared against
7506 <filename>LAYERVERSION_anotherlayer</filename>.

7510 An error is produced if any dependency is missing or the

7512 This variable is used in the

7514 suffixed with the name of the specific layer (e.g.
