/**
* Get the tag for a DICOM element. This method supports dcm4che names as well as hex strings,
* with or without enclosing parentheses or square brackets and with or without a comma separating
* the group and the element numbers. This method also supports private group names defined in the
* script. This method differs from the DicomObject method of the same name in that it also
* supports names for private group elements in the form 0009[ID]02, where ID is the block owner
* ID. Examples of element specifications containing block owner IDs are:
*
* <ul>
* <li>9,[blockID]02
* <li>(9,[blockID]02)
* <li>[9,[blockID]02]
* <li>0009[blockID]02
* </ul>
*
* @param name the dcm4che element name or coded hex value.
* @return the tag, or zero if the name cannot be parsed as an element specification
