type="Transform", this AttributeResolver applies one or more regular expressions to an input attribute, either replacing its values, or generating new attributes.
The transforms to apply are specified using
<Regex> child elements. Each element specifies a transform rule to apply to each value of the designated input attribute(s).
match attribute specifies a regular expression to match against the input value(s). It can contain parentheses to specify capturing groups. The content of the element is a replacement expression that can contain group placeholders to match the capturing groups (e.g., $1, $2, etc.). If the expression does not match, the value is passed through unchanged.
dest attribute, if present, specifies the ID of a new attribute to create that will contain the transformed values. If not present, the transformed values replace the original attribute's values "in-place", if and only if the original attribute was a "simple" string-valued attribute. Other attribute types with more complex values cannot be transformed in-place.
caseSensitive attribute specifies whether the containing
match expression is to be interpreted case-sensitively. It is a boolean that defaults to "true".
|string||Y||Identifies the attribute ID of the input attribute(s) to process. All attributes with an ID that matches the value will be evaluated.|

This is a bit overly simplistic, and assumes the source values are in a particular format.
The example parses a displayName attribute in the form "first last" and produces two separate attributes to carry each value alone, while also reversing the order in place.
