Fix for 2531927 debug mode problem

[fix #2529428] Fix IE9 XML errors. 1. Though IE9 apparently now has DOMParser API, it doesn't have XPath support and the document it returns does not have getAttribute(). So stick with Microsoft.XMLDOM. 2. context.childNodes -> context.children since IE9 was picking up text nodes.

Cleanup of submodule declarations for apidocs.

DataType apidoc changes only.

Y.log() src -> module or submodule names.

Account for SF's lenient parsing of string to XML.

Broken line breaks.

Finish commiting new files for separating Number and XML modules into parse/format submodules. Also, decimalPlaces needs to be validated to be between 0 and 20.
