> There is an inconsistency between the native JSF parser and Seam's Interpolator, which is used to resolve page descriptions in the pages.xml file, amongst other places.
> If you need to place a # character just before the value binding expression, you must escape with with a backslash (\) according to the EL specification (i.e. \##{contextVariable}). However, the Interpolator chokes when it encounters this syntax.
> The Interpolator should be changed to ignore a # sign if escaped.
