/** 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 occurences of the same attribute in an element but the last
are removed.
3) Line breaks represented by a single <br> element (without matching
</br> element) are replaced by a literal LF character.
