-Given a PML file, how do I validate it? I always forget... Please provide me with the one-liner to do the validation. +Given a PML file, how do I validate it?
  
 +For most purposes, a libxml2 (DOM) based validator
 +<code>/f/common/exec/validate_pml --pml-dir /f/common/share/pml --path /f/common/share/tred file_to_validate</code>should work fine and fast.
  
 +For huge files, use<code>/f/common/exec/validate_pml_stream --path /f/common/share/tred file_to_validate</code>which is based on Jing (SAX); Jing has no Zlib or stdin support, so some space in /tmp will be needed for temporary files.
 +Both scripts have decent user documentation. See inside the scripts if interested in the implementation details.

 Most probably you'll still face problems when accessing attributes of XML elements, because namespacing rules apply differently to attributes and elements. You'll need to read XML (Namespaces) specification. Most probably you'll still face problems when accessing attributes of XML elements, because namespacing rules apply differently to attributes and elements.
