Usage

Arguments

tag	a tag object.
...	a collection of attributes.
.cssSelector	A character string containing a CSS selector for targeting particular (inner) tags of interest. At the moment, only a combination of type (e.g, div), class (e.g., .my-class), id (e.g., #myID), and universal (*) selectors within a given simple selector is supported. Note, if .cssSelector is used, the returned tags will have their $children fields flattened to a single list() via tagQuery().
