This WARNING is important.

xmltool uses the schema to determine 1) where it can remove ignoreable 
whitespace from the input document and 2) where it can safely add 
ignoreable whitespace, that is, the indentation and newlines.

Without a schema, you simply cannot get any satisfactory result.

Please try:

C:\xxx\> xmltool indent -s 
XXE_INSTALL_DIR\addon\config\docbook51\rng\V5.1\docbook.rng -indent 2 
-maxlinelength 78 -v -o manual\4-wire-bridging-submodule.xml 
manual\4-wire-bridging-submodule.xml

Notice the extra "-s 
XXE_INSTALL_DIR\addon\config\docbook51\rng\V5.1\docbook.rng" option.

***********************************************************************
--> However, It's really not a good idea to overwrite your input file!

C:\xxx\> xmltool indent -s 
XXE_INSTALL_DIR\addon\config\docbook51\rng\V5.1\docbook.rng -indent 2 
-maxlinelength 78 -v manual\4-wire-bridging-submodule.xml

will create indented "manual\4-wire-bridging-submodule.xml" and save 
original file as "manual\4-wire-bridging-submodule.xml.BAK".
