 The concept `LinearCellComplex` represents a linear cell complex in dimension `d`, in an ambient space of dimension `d2`. This is a model of the concept of `GenericMap` adding a requirement to ensure that each vertex of the map is associated with a model of `CellAttributeWithPoint`.

 The concept `SpatialSeparator` defines the requirements for
 a separator.
 
-\cgalAdvancedBegin
 A separator is a `d-1`-dimensional subspace that
 separates a `d`-dimensional space into two parts.  One part of
 space is said to be on the negative side of the separator and the
 other part of space is said to be on the positive side of the
 separator.
