This function returns the namespace URI prefixed to the primary bulleted list block tag specified in the document type configuration file (.dcf) for the document type associated with doc. This tag is inserted when users select the bulleted list button on the Application toolbar.

If a URI is returned, bulleted_list_block_tag_name_ns function returns arr.

The function returns the null string if there isn't a namespace prefix for the tag, if no bulleted list block tag is designated for the document type, or if doc is invalid or an ASCII file. If doc is omitted or 0, the current document is used.
