It appears that in the process of merging this:

...into the above ID, the following key parts were lost:

 * The definition of what is a "valid URL", defined such that an IRI is 
   only a "valid URL" if its query part will be interpreted according to 
   the IRI spec according to the URL parsing algorithm.

 * The definition of what is an "absolute URL", defined such that even 
   invalid strings can be valid URLs. For example, the following: not a "valid URL" but needs to be an "absolute URL".

 * The definition of how to determine whether the following components are 
   present in, and how to obtain their value from, a string that may not 
   be a "valid URL":


 * The definitions for how to resolve a string to an "absolute URL" when 
   the original string is not necessarily a "valid URL".

(I use the term "URL" here in the HTML5 sense, which has varyingly been 
called a Web Address or an HRef in related work.)

The following issues also exist in the draft:

 * "is the script's character. encoding" has a typo (misplaced ".")

 * Step 8 in the algorithm for parsing HRefs appears to be a corrupted 
   form of the definition of <hostport> from the old HTML5 text. The new 
   text as phrased appears to be meaningless.

 * It appears that the parsing algorithm is destructive, in that the 
   results will not be isomorphic with the input. For example, the 

   ...will turn into:

   ...which, once the "resolving" algorithm is reintroduced, will be 
   incompatible with implemented practice.
