\arguments{
  \item{_tag_name}{HTML tag name}

  \item{varArgs}{List of attributes and children of the
  element. Named list items become attributes, and unnamed
  list items become children. Valid children are tags,
  single-character character vectors (which become text
  nodes), and raw HTML (see \code{\link{HTML}}). You can
  also pass lists that contain tags, text nodes, and HTML.}

  \item{tag}{A tag to append child elements to.}

  \item{child}{A child element to append to a parent tag.}

  \item{...}{Unnamed items that comprise this list of
  tags.}

  \item{list}{An optional list of elements. Can be used
  with or instead of the \code{...} items.}
}
\value{
An HTML tag object that can be rendered as HTML using
  \code{\link{as.character}()}.
}
\description{
\code{tag()} creates an HTML tag definition. Note that all of the valid HTML5
tags are already defined in the \code{\link{tags}} environment so these
functions should only be used to generate additional tags.
\code{tagAppendChild()} and \code{tagList()} are for supporting package
authors who wish to create their own sets of tags; see the contents of
bootstrap.R for examples.

# Can also convert a regular list to a tagList (internal data structure isn't
# exactly the same, but when rendered to HTML, the output is the same).

          tags$h2("Header text"),
          tags$p("Text here"))
