The following tab is available in the Chain Root Node Properties dialog box:
Use the [Node Name] tab to specify the name of the Chain Root node.
If the node is linked, the node name is displayed in the [Node name for chain root] text box. If it is not linked, then "Unknown" is displayed here. To change the node name, edit the name that is displayed. To specify a new name for a node that is not linked, delete "Unknown" and input the desired name. Conversely, to delete the node name, delete the name that is displayed in the text box. Please note that ASCII characters from "!" (0x21) to "~" (0x7e) can be used for node names. In addition, node names cannot contain spaces, nor can they contain kanji, hiragana or katakana characters.
