Interpret MathML inputs without evaluating them:

Wolfram Language code: Interpreter["InactiveMathMLExpression"]["<math><mrow><mn>2</mn><mo>+</mo><mn>2</mn></mrow></math>"]
Wolfram Language code: Interpreter["InactiveMathMLExpression"]["<math><mrow><mi>sin</mi><mo>&#8289;</mo><mo>(</mo><mi>0</mi><mo>)</mo></mrow></math>"]

No evaluation is attempted when matching the choices:

Wolfram Language code: Interpreter[Restricted["InactiveMathMLExpression", {{True, False}}]]["<math><mrow><mn>2</mn><mo>==</mo><mn>2</mn></mrow></math>"]
Wolfram Language code: Interpreter[Restricted["InactiveMathMLExpression", {{Inactivate[Equal[2, 2]], False}}]]["<math><mrow><mn>2</mn><mo>==</mo><mn>2</mn></mrow></math>"]

By default, all symbols are allowed. Restrict to a list of allowed symbols:

Wolfram Language code: Interpreter[Restricted["InactiveMathMLExpression", {Plus}]]["<math><mrow><mn>2</mn><mo>+</mo><mn>2</mn></mrow></math>"]
Wolfram Language code: Interpreter[Restricted["InactiveMathMLExpression", {Plus}]]["<math><mrow><mn>2</mn><mo>*</mo><mn>2</mn></mrow></math>"]

By default, new symbols are created in $Context, but a custom context can be specified:

Wolfram Language code: Interpreter[Restricted["InactiveMathMLExpression", Automatic, Automatic, Automatic]]["<math><mrow><mn>x</mn></mrow></math>"] Context[x]
Wolfram Language code: Interpreter[Restricted["InactiveMathMLExpression", Automatic, Automatic, "mycontext`"]]["<math><mrow><mn>y</mn></mrow></math>"] Context[x]

Specify contexts for the allowed and output symbols:

Wolfram Language code: Global`z = 10; Interpreter[Restricted["InactiveMathMLExpression", Automatic, {"Global`", "System`"}, "Global`"]]["<math><mrow><mi>sin</mi><mo>&#8289;</mo><mo>(</mo><mi>z</mi><mo>)</mo></mrow></math>"]

Prevent the creation of any new symbol:

Wolfram Language code: Interpreter[Restricted["InactiveMathMLExpression", Automatic, Automatic, None]]["<math><mrow><mn>2</mn><mo>+</mo><mn>2</mn></mrow></math>"]
Wolfram Language code: Interpreter[Restricted["InactiveMathMLExpression", Automatic, Automatic, None]]["<math><mrow><mn>z</mn><mo>+</mo><mn>2</mn></mrow></math>"]
