HTML5 Custom Data Attributes
Fluid should support the use of HTML5 Custom Data Attributes as described in the W3C Specification1.
The Patterns need to be changed so that attributes with "-" are actually identified as such. Currently fluid breaks with such attributes.
Furthermore "data-*" won't fit into the current way of registering attributes with a full name and type. Fluid will probably need a solution which allows a registration of patterns for attributes. (always with string as type?)
