Syntax

public class MacroUsageContextProcessor : IProcessesExpressionContext

Remarks

A metal:use-macro attribute indicates that the current DOM node should be replaced by an expanded METAL macro. The macro to use as the replacement is indicated via an expression which is the value of the use-macro attribute.

Macro expansion is handled by the service IExpandsMacro. This includes both filling slots which are defined in the used macro and also performing macro extension, if applicable.
