244 * Background:
245 * Input GET/POST variables in PHP may have their quotes escaped with "\" or not depending on configuration.
246 * TYPO3 has always converted quotes to BE escaped if the configuration told that they would not be so.
247 * But the clean solution is that quotes are never escaped and that is what the functions below offers.
248 * Eventually TYPO3 should provide this in the global space as well.

2456 * The XML output is optimized for readability since associative keys are used as tagnames.
2457 * This also means that only alphanumeric characters are allowed in the tag names AND only keys NOT starting with numbers (so watch your usage of keys!). However there are options you can set to avoid this problem.
2458 * Numeric keys are stored with the default tagname "numIndex" but can be overridden to other formats)
2459 * The function handles input values from the PHP array in a binary-safe way; All characters below 32 (except 9,10,13) will trigger the content to be converted to a base64-string
2460 * The PHP variable type of the data IS preserved as long as the types are strings, arrays, integers and booleans. Strings are the default type unless the "type" attribute is set.
2461 * The output XML has been tested with the PHP XML-parser and parses OK under all tested circumstances with 4.x versions. However, with PHP5 there seems to be the need to add an XML prologue a la <?xml version="1.0" encoding="[charset]" standalone="yes" ?> - otherwise UTF-8 is assumed! Unfortunately, many times the output from this function is used without adding that prologue meaning that non-ASCII characters will break the parsing!! This suchs of course! Effectively it means that the prologue should always be prepended setting the right characterset, alternatively the system should always run as utf-8!
2462 * However using MSIE to read the XML output didn't always go well: One reason could be that the character encoding is not observed in the PHP data. The other reason may be if the tag-names are invalid in the eyes of MSIE. Also using the namespace feature will make MSIE break parsing. There might be more reasons...
