BUGS AND PROBLEMS
   I list what I found. There may be any other bugs and problems.
   1. Item.pm: decimals specification is based on TDnet and EDINET.
   2. Taxonomy.pm
      DTS(Discoverable Taxonomy Set)
      XBRL2.1: 3.2
      DTS rules of discovery: ONLY the followings are referenced.
        1. referenced directly from an XBRL Instance using the <schemaRef> element.
        2. referenced from a discovered taxonomy schema via an XML Schema import element.
        3. referenced from a discovered Linkbase document via a <loc> element.
        6. referenced from a discovered taxonomy schema via a <linkbaseRef> element.
   3. Role files, reference files and gla files are not parsed.
   4. XBRL2.1: 3.5.3.7.2
      href of locator may be relative.
   5. XBRL2.1: 3.5.4
      abc.xsd#element(/1/14)... will not work.
   6. I cannot find a rule to decide which label is used for definition tree.
