tdom-dev 0.8.3-1 (arm64 binary) in ubuntu bionic

 This package contains the header files and development libraries for
 tDOM, a fast XML/DOM/XPath/XSLT extension for Tcl. tDOM takes
 advantage of Expat, the XML parser from James Clark. It comes with a
 (partial) DOM-I and DOM-II implementation in C for maximum performance
 and minimum memory need. A very complete, compliant and fast XPath
 implementation is provided. A fast XSLT implementation in C
 completes the feature set.
