  <!-- Comments by AK4OL:

In order to minimize exciting bugs in existing software, simple, already used, types such as xsd:decimal and xsd:string were used for most of the added fields.   Existing code may not know how to handle xsd:all, xsd:anyURI, xsd:annotation/xsd:documentation etc.)

All occurances of xsd:sequence in this file should really be xsd:all.  The program has no business enforcing a specific order.  Interoperability dictates that you generate fields in the order listed but take them in any order; i.e. demand more of yourself than you demand of others.  Strictly validate your output, not your input.  Fools often get this backwards and destroy one of the primary advantages of XML).  Interoperability also dictates that you do not choke on unrecognized fields as the program currently does; this means, for example, that version 1.0 will choke on version 2.0 files or files generated by other programs which use the same format but add extensions.   This makes chirp files almost useless for information interchange between users or even between different machines used by the same user which may have different versions.  Warn that there is unrecognized data but parse all the data you can.   validate_doc() must be disabled or modified to produce warnings only.  It is ok to require the file to be well formed xml but it is not ok to fail if their are unrecognized fields or the field order is different.

Chirp currently generates attrociously formatted XML - all on one line.   Chirp can read properly formatted xml.

sudo apt-get install libxml-tidy-perl

xmltidy somefile.chirp   # warning: modifies in place

  Chirp already has the ability to hide fields which are not of interest.  In addition, these additional fields will not be displayed if you are editing a radio file, just a chirp file.

   location attribute on memoryType should be optional.   If data has been imported, it may be meaningless or absent.

In xml.py

      rf.memory_bounds = (0, 1000)

is probably a bug.   Some radios have more than 1000 memories.
