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.
