The following tables compare XHTML 1.1 compatibility and support for a number of layout engines.
XHTML 1.1 which is mainly a modularization of XHTML 1.0, is composed of 20 element modules (7 of which are submodules), including the additional Ruby Annotation Module, and two attribute modules (Server-side Image Map Module and Intrinsic Events Module).

| Value | Meaning |
|---|
| Yes | Indicates that the layout engine fully supports this property/element when valid values are used. |
| No | Indicates that the property/element is completely ignored. |
| Partial | Indicates that the property/element is understood, but that not all values are supported. Supported values are implemented correctly. |
| Incorrect | Indicates that the property/element is understood, but that it is not implemented correctly in all cases. |
| Experimental | Indicates that the property/element is understood, but supported under an alternate name. May be incomplete or buggy. |
| Dropped | Indicates that the property/element is no longer supported. |
| Nightly build | Indicates that the property/element is supported to some extent in an experimental/nightly build. Future support is expected. |
