        Arguments:
8c93bb
8c93bb
        name: The XHTML tag's name. Notice that this function doesn't
8c93bb
            verify nor validate the XHTML tags you provide. It is up
8c93bb
            to you write them correctly considering the XHTML standard
8c93bb
            definition.
8c93bb
8c93bb
        attrs: The XHTML tag's attribute. Notice that this function
8c93bb
            doesn't verify the attributes assignation to tags. You
8c93bb
            need to know what attributes are considered valid to the
8c93bb
            tag you are creating in order to build a well-formed XHTML
8c93bb
            document. Such verification can be achived inside firefox
8c93bb
            browser through the `firebug' plugin.
8c93bb
8c93bb
        indent: The XHTML tag's indentation (Optional). This argument
8c93bb
            is a list of two numerical values. The first value in the
8c93bb
            list represents the amount of horizontal spaces between
8c93bb
            the beginning of line and the opening tag.  The second
8c93bb
            value in the list represents the amount of vertical spaces
8c93bb
            (new lines) between tags.
8c93bb
8c93bb
        content: The XHTML tag's content (Optional). This argument
8c93bb
            provides the information the tag encloses. When this
8c93bb
            argument is empty, tag is rendered without content.
8c93bb
8c93bb
        has_child: The XHTML tag has a child? (Optional). This
8c93bb
            argument is specifies whether a tag has another tag inside
8c93bb
            (1) or not (0).  When a tag has not a child tag,
8c93bb
            indentation is applied between the tag content and the
8c93bb
            closing tag provoking an unecessary spaces to be shown.
8c93bb
            Such kind of problems are prevented by setting this option
8c93bb
            to `0'. On the other hand, when a tag has a child tag
8c93bb
            inside, using the value `1' will keep the closing tag
8c93bb
            indentation aligned with the opening one.

        This function encapsulates the construction of XHTML tags.
8c93bb
        Use this function wherever you need to create XHTML tags. It
8c93bb
        helps to standardize tag constructions and their final output
8c93bb
        and. This function provides a consistent way of producing
8c93bb
        output for XHTML documents.
