Detailed Description

An input stream class for VML streams, implementing the UNO interface com.sun.star.io.XInputStream needed by the Expat XML parsers.

This stream reads the data from the input stream passed to the constructor, and parses all XML elements for features unsupported by the current Expat XML parser:

1) All elements that have the form '<![inst]>' where 'inst' is any string not containing the characters '<' and '>' are stripped from the input stream.

2) Multiple occurrences of the same attribute in an element but the last are removed.

3) Line breaks represented by a single
element (without matching element) are replaced by a literal LF character.
